Contact more customers, there will always be a lot of questions, such as a user asked, ferrite magnet can be saved for how long? Does oxidation of ferrite affect its properties?

Today I will reply to these two questions.

 

Ferrite, also known as permanent magnet ferrite, chemically known as ferric oxide, is already an oxide of iron, and it is difficult to be oxidized again. For the magnetic ring, its characteristics are long-term, there will be no deterioration, but put for a long time, there will be residue on the surface - some powder, this is a normal phenomenon, does not hinder its characteristics.

 

As we all know, ferrite magnet is made of a variety of magnetic materials, so put for a long time, the magnet will appear powder, which is what we say in the industry oxidation, but this does not affect its magnetic properties and impedance characteristics. The magnet will also be easy to oxidize when it encounters moisture, especially in wet weather. If the magnetic ring of the packaging is not sealed well and the moisture runs into the carton, it will also lead to oxidation of the magnetic ring.

 

Many people will ask, the magnet in production is not through water to clean the surface? How can also be afraid of water, of course, the magnetic ring is through the water to wash off the dirty surface, but after cleaning, the magnet to enter the oven to dry water, so just made of the magnet, not oxidation, and just washed out of the magnetic ring appearance, shiny!

 

Recommendation for Magnet Selection

 

1. Project Assessment

Begin by clarifying the application requirements:

● Application Scenario: Identify the purpose (e.g., industrial machinery, consumer electronics, medical devices).

● Force Requirements: Determine the necessary magnetic strength (e.g., high-precision motors require strong magnets like NdFeB)

● Temperature Range: Select materials based on operating temperatures. For example:

● N-series NdFeB: Suitable for ≤80°C.

● H/SH/UH/AH-series NdFeB: Higher temperature resistance (up to 230°C)

● Environmental Conditions: Consider corrosion risks (e.g., NdFeB requires nickel or epoxy coatings for humidity resistance)

2. Magnet Material Selection

Compare key magnetic materials (weakest to strongest):

1. Rubber Magnets: Low cost, flexible (ideal for signage, calendars, crafts)

2. Ferrite Magnets: Affordable, widely used in motors and speakers

3. AlNiCo Magnets: High-temperature tolerance (~500°C), stainless appearance (suitable for instruments)

4. Samarium Cobalt (SmCo): Heat-resistant (150–300°C), brittle but durable in harsh environments

5. Neodymium (NdFeB): Highest magnetic strength, cost-effective, but prone to oxidation (requires coatings)

3. Supplier Communication Strategy

When contacting clients (e.g., manufacturers or distributors):

● Key Questions to Ask:

● Do you provide customized shapes (e.g., discs, rings, blocks)?

● What certifications do your products hold (e.g., ISO, RoHS)?

● Can you share test reports for magnetic performance and durability?

● Sample Request: Request samples to verify quality and compatibility with your application.

● Cost and Lead Time: Compare pricing and delivery timelines across suppliers.

When it comes to protecting valuable products during storage or transport, EVA foam inserts are one of the most famous choices.  They provide excellent cushioning, durability, and a tidy, professional appearance.  However, achieving the perfect fit requires more than just cutting foam to shape.  It is about precision design, smart material selection, and attention to every detail.

 

At Yisi Packing, we specialize in OEM and ODM EVA packaging solutions, helping clients design inserts that protect, display, and enhance their products.  Based on our years of solid experience, here are five essential tips for designing EVA inserts that fit perfectly.

 

1. Start with Accurate Measurements

 

The most important step in creating a perfect EVA insert is obtaining precise product dimensions.  Even a few millimeters of difference can affect how securely an item fits.

Before design or production begins:

 

• Use digital calipers or 3D scans to measure your products.

• Consider every dimension, it is including protruding parts, curves, or handles.

• If you have multiple products in one case, plan for equal spacing to ensure balance and visual appeal.

 

At Yisi Packing, our design team often requests physical samples or detailed CAD drawings from clients.  This ensures that every insert is engineered to fit exactly, avoiding loose gaps or tight squeezes that could damage products.

 

2. Choose the Right EVA Foam Density

 

EVA foam comes in a range of densities, and selecting the right one directly impacts the protection level and overall appearance.

 

• Low-density EVA is soft and lightweight, it is ideal for lightweight or fragile products such as cosmetics, small electronics, or promotional packaging.

• Medium-density EVA offers balanced cushioning and support, making it a great choice for tools, instruments, or sports accessories.

• High-density EVA is firm and durable, it is perfect for precision instruments, cameras, or heavy equipment.

 

At Yisi Packing, we help customers match the right foam type and density for their product’s specific requirements, ensuring optimal performance and a professional finish.

 

3. Optimize the Insert Layout for Function and Aesthetics

 

Designing EVA inserts isn’t only about protection, it’s also about presentation.  A well designed layout can elevate your brand image.

Here are a few layout tips:

 

• Arrange products in a logical sequence, especially for toolkits or multi piece sets.

• Leave consistent spacing between items for visual harmony.

• Add finger notches or pull tabs for easier removal.

• Include cut outs for accessories or cables to keep everything organized.

 

Yisi Packing’s design team uses CAD software to visualize the insert layout and adjust positioning before production.  This allows us to confirm both the appearance and functionality with clients before cutting the first piece.

 

4. Consider Lamination and Surface Finishes

 

A high quality finish makes your EVA packaging stand out.  You can enhance both beauty and durability through lamination or surface treatments such as:

 

• Velvet or fabric lamination for a luxury, soft touch feel.

• PU or nylon lamination for added durability and water resistance.

• Color matching and logo embossing to reflect your brand identity.

 

These options not only improve the visual appeal but also extend the product’s lifespan.  Yisi Packing offers multiple lamination choices, allowing customers to achieve the perfect balance of protection and style.

 

5. Prototype and Test Before Mass Production

 

Even with perfect design files, small adjustments may still be needed.  Always create a prototype before full scale production.  This allows you to test:

 

• Product fit and ease of removal

• Foam density and comfort

• Overall visual appearance and color consistency

 

At Yisi Packing, we provide rapid sample prototyping services so clients can physically evaluate their inserts and suggest improvements before confirming the final mold.  This step minimizes costly revisions and ensures a perfect result.

 

6. Final Advice

 

Designing EVA inserts that fit perfectly requires a mix of precision, experience, and innovation.  From accurate measurements to careful material selection and thorough testing, every step contributes to superior packaging performance.

 

As a professional OEM EVA packaging manufacturer, Yisi Packing helps clients around the world create customized EVA inserts for tools, electronics, cosmetics, and many other industries.  Whether you need simple foam cut outs or complex multi layer designs, our team ensures your products are protected and presented perfectly.

When our customers consider creating high quality, custom protective cases, EVA foam (Ethylene Vinyl Acetate) stands out as one of the most reliable materials available.  Whether it’s for electronics, medical devices, or high end equipments, the precision, durability, and versatility of EVA foam make it the preferred choice for many industries.  At Yisi Packing, we specialize in designing and manufacturing custom EVA foam cases that provide the highest level of protection for your products, ensuring they arrive at their destination in top condition.  But what exactly makes EVA foam the best material for custom cases?  Let’s go into its unique qualities and why it’s an ideal option for your packaging needs.

 

1. Shock Absorption and Impact Resistance

 

One of the key reasons why EVA foam is so popular in protective case design is its superior shock absorption properties.  The foam is capable of absorbing and dispersing impact forces, preventing damage to delicate and valuable items inside.  Whether you’re shipping electronics like cameras and laptops or sensitive medical equipment, the cushioning effect of EVA foam ensures that external forces like drops or bumps won’t cause damage.

 

At Yisi Packing, we use cutting edge techniques to craft foam inserts that snugly fit around your product’s contours, providing targeted protection against accidental shocks or impacts.  This high precision fit ensures that your items stay safe and secure, even during rough handling or transport.

 

2. Lightweight Yet Durable

 

Despite its remarkable protective qualities, EVA foam is very lightweight.  This makes it ideal for businesses that want to minimize the weight of their packaging while still providing all round protection.  Unlike heavy, rigid alternatives like metal or hard plastics, EVA foam maintains a lightweight profile, which can also contribute to reducing shipping costs.

 

In addition to being light, EVA foam is also durable and can withstand wear and tear over time.  It doesn’t crack or degrade under normal conditions, making it suitable for long term use.  Whether you're creating custom cases for consumer electronics, industrial tools, or instruments that will be used frequently, EVA foam ensures long lasting durability without adding unnecessary bulk.

 

3. Customization and Precision Cutting

 

One of the outstanding features of EVA foam is its versatility in customization.  Unlike many other materials, EVA foam can be easily cut, shaped, and molded to fit the exact specifications of your product.  At Yisi Packing, we use advanced precision cutting techniques such as laser cutting and CNC routing to create details foam inserts that perfectly match the dimensions and contours of your items.

 

This ability to create highly detailed, custom shapes ensures that every case provides a perfect fit, which is critical for products that require extra protection.  Whether you need foam inserts for a small piece of medical equipment or a large, complex device, we can craft the ideal solution for your needs.

 

4. Water Resistance and Insulation Properties

 

Another reason EVA foam is favored for custom cases is its excellent water resistance and insulation properties.  The material naturally repels moisture, preventing water damage to sensitive products during transportation or storage.  This makes it an ideal choice for cases that will be exposed to extreme weather conditions or humid environments, such as outdoor tools or electronics.

 

Additionally, EVA foam provides thermal insulation, which helps regulate the temperature inside the case.  This can be particularly valuable for products that need to be kept within a specific temperature range, such as batteries, precision instruments, or medical supplies need the temperature control.

 

5. Eco Friendly and Non Toxic

 

As businesses and consumers become increasingly concerned with sustainability, the eco friendliness of EVA foam offers another significant advantage.  Unlike other plastic based materials, EVA foam is free from toxic chemicals like PVC, making it a safer option for both consumers and the environment.  It is also recyclable in many cases, offering a more sustainable alternative to traditional plastic cases.

 

At Yisi Packing, we are committed to minimizing our environmental impact.  By using EVA foam, we ensure that our custom cases not only provide the best protection for your products but also align with global sustainability standards.

 

 

In summary, from its shock absorbing properties to its lightweight and durable nature, EVA foam is certainly one of the best materials for creating high precision custom cases.  Its versatility, ability to be easily customized, and eco friendly attributes make it an excellent choice for businesses across various industries.  At Yisi Packing, we specialize in delivering top notch EVA foam case solutions that offer reliable protection for your valuable products.  No matter the size, shape, or complexity of your items, we can design and manufacture a custom EVA foam case that meets your exact specifications, ensuring that your products arrive safely and securely.

In the beauty industry, cosmetic products play a significant role in many people's daily routines. From skincare creams to hair gels, these products often come packaged in various forms, including bottles, jars, and tubes. Among these packaging options, cosmetic tubes have gained popularity due to their convenience and portability.

Runk manufactures produces all its cosmetic packaging tubes/ bottles/ jars from sustainable, eco-friendly materials.

 

 

Understanding Cosmetic Tubes

Cosmetic tubes are typically made from a variety of materials, with plastic being the most common. The most frequently used type of plastic for cosmetic tubes is polyethylene (PE), a material that offers flexibility, durability, and protection for the product inside. While these tubes provide practicality for consumers, their impact on the environment raises concerns.

 

 

• PE (Polyethylene) – thin, flexible “squeeze” tubes used for cleansers, lotions, masks
• Aluminum – collapsible metal tubes common for hair color, pharma-style creams
• ABL (Aluminum-Barrier-Laminate) – plastic + aluminum “sandwich” for high-barrier formulas
• PBL (Plastic-Barrier-Laminate) – all-plastic multilayer with EVOH or PP barrier

At Runk, our cosmetic packaging tubes are predominantly manufactured from mono-material PE and PP, ensuring full recyclability and a measurable reduction in environmental impact.

 

Consumer Responsibility

As consumers, we play a crucial role in the push for sustainable practices in the beauty industry. By choosing products in recyclable or sustainable packaging, we can drive demand for eco-friendly options and encourage brands to adopt environmentally responsible practices.

 

The recyclability of cosmetic tubes is a complex issue that requires a concerted effort to solve. Runk will continue to use environmentally friendly materials to produce cosmetic packaging tubes for a more sustainable future and reduce the environmental impact of cosmetics.

The beauty industry is always looking for smarter packaging solutions. Cosmetic squeeze tubes are gaining attention, but do they hold the key to tomorrow's beauty packaging? Let's explore.

 

 

Sustainability Meets Practicality

 

Brands now prioritize eco-friendly choices, and squeeze tubes deliver. Many are made with recycled materials or designed to be fully recyclable. They reduce waste too—users can squeeze out every last drop, unlike jars that trap product. This combination of green values and practical use makes them a strong contender.

 

Convenience for On-the-Go Lifestyles

 

Modern consumers want products that fit their busy lives. Squeeze tubes excel here. They are lightweight, easy to carry in purses or travel bags, and mess-free. A simple press dispenses the right amount, whether it's lotion, serum, or foundation. This ease of use keeps customers coming back.

 

Flexibility for Brand Storytelling

 

Tubes offer more than function—they're a canvas for brands. Companies can print vibrant designs, ingredient lists, or brand messages directly on the surface. This flexibility helps products stand out on shelves and connect with shoppers. From minimalist to bold, tubes adapt to any brand's identity.

Squeeze tubes check many boxes: sustainability, convenience, and branding potential. As the beauty industry evolves, these tubes aren't just a trend—they're a forward-thinking choice that meets both brand and consumer needs. The future of beauty packaging might just be in the palm of your hand.

Consumers today care deeply about sustainability, and brands need to respond by making eco-friendly choices, especially in packaging. A common question is: are hand cream tubes recyclable? The answer varies based on the tube’s materials.

 

 

The Recycling Challenge of Traditional Tubes

 

Many hand cream tubes on the market use multi-layered materials. Manufacturers combine different plastics or pair plastic with other substances to boost durability and barrier properties. However, this complexity creates a major recycling hurdle. Recycling facilities struggle to separate these mixed materials, often sending such tubes to landfills instead. As a result, traditional hand cream tubes contribute to environmental waste.

 

Sustainable Materials for Recyclable Tubes

 

Forward-thinking hand cream tube manufacturers now offer better alternatives. Single-material plastic tubes simplify the recycling process. Since recycling plants can easily process one type of plastic, these tubes have a higher chance of becoming new products. Aluminum tubes are another great option. They are infinitely recyclable and retain their quality through repeated recycling cycles, making them an eco-friendly choice for brands.

 

How Brands Can Make a Difference

 

Brands play a crucial role in promoting sustainability. By partnering with a hand cream tube manufacturer that specializes in recyclable materials, brands can reduce their environmental footprint. Additionally, educating consumers about proper disposal methods through clear packaging instructions helps ensure recyclable tubes actually reach recycling facilities. Choosing sustainable packaging not only benefits the planet but also enhances a brand’s reputation among eco-conscious customers.
