Considerations:
EPE is a type of expanded plastic material, so its recycling generally depends on suitable plastic collection and processing facilities.
Its low density and relatively large volume may also create additional challenges during collection, хранилище, and transportation.
For brands looking to move toward paper-based packaging materials, EPE may not fully meet their material transition goals.
4. EVA Foam Inserts: Flexible Structure and a Precise Fit
EVA is a flexible polymer foam material known for its elasticity and cushioning properties. It can be cut, molded, or engraved into custom compartments that closely match product shapes.
Its combination of flexibility and structural stability makes EVA a popular option for packaging products that require a secure fit and reliable support.
Key Features:
- Good flexibility and elasticity.
- Custom-cut compartments for different product contours.
- Provides cushioning and support for packaged items.
- Commonly used for electronics, precision instruments, ювелирные изделия, вино, and premium gift packaging.
Considerations:
EVA is a synthetic polymer foam, and its recycling depends on specialized processing methods and suitable collection channels. Different formulations, покрытия, and composite structures can also affect its recyclability.
Brands seeking alternatives to conventional foam packaging may consider paper-based options such as molded pulp inserts.
5. Molded Pulp Inserts: A Paper-Based Solution for Sustainable Packaging
Вставки из формованной целлюлозы, also known as molded fiber inserts, are generally made from recycled paper pulp, paper fibers, or other suitable plant-based fibers. Through a molding process, the material is formed into custom shapes that fit different products.
Unlike conventional plastic and foam inserts, molded pulp is primarily fiber-based. It can provide structural support and cushioning while offering the potential to be recycled through appropriate paper fiber recycling systems.
As brands place greater emphasis on sustainable packaging, molded pulp inserts are becoming an increasingly relevant option for electronics, косметика, personal care products, подарки, and everyday consumer goods.
Key Features:
- Paper-Based Materials: Primarily made from paper pulp or plant fibers, providing an alternative to conventional plastic inserts.
- Возможность вторичной переработки: Can be compatible with paper fiber recycling systems when material composition and local recycling requirements are met.
- Custom Molded Design: Custom molds can be developed according to product dimensions, формы, and placement requirements.
- Product Protection: Properly designed structures help hold products in place and provide support and cushioning.
- Versatile Applications: Suitable for electronics, skincare products, косметика, подарки, household goods, and various consumer products.
Considerations:
The performance of molded pulp inserts depends on fiber materials, структурный проект, manufacturing processes, and the products being packaged.
For particularly heavy or fragile products, the insert structure should be carefully designed and tested to ensure sufficient protection.
Molded pulp also has a different surface appearance from plastic and foam materials, making it particularly suitable for brands that value paper-based materials, a clean presentation, and sustainable packaging concepts.
