EVA has the characteristics of flexibility, elasticity, chemical corrosion resistance, and adhesion, and has a wide range of application scenarios, mainly including:
1. Packaging field
1. Produce food packaging film and daily necessities packaging film (high transparency, impact resistance).
2. Co extrude with LLDPE to produce stretch film for container packaging or bundling.
2. Adhesive field
As a hot melt adhesive, it is used in book binding, wood processing, and packaging industries (with fast curing and strong adhesion).
3. Shoe material field
1. Make shoe soles (soft, shock-absorbing, comfortable) alone or by blending with other materials.
4. Wire and cable field
1. As an insulation layer or sheath (with good insulation and strong flexibility).
5. Photovoltaic industry
As an encapsulation film for photovoltaic modules, it has high transparency, strong weather resistance, protects the solar cells, and improves power generation efficiency.
6. Construction field
1. Make sealant, waterproof roll and thermal insulation materials (such as EVA foam plastic for wall insulation and roof waterproofing).
7. Toys and crafts
1. Make soft toys and decorative materials (with strong plasticity and high safety).
EPE (Expanded Polyethylene) is a material composed of countless independent bubbles generated by physical foaming of low-density polyethylene (LDPE). It is characterized by light weight, good cushioning, earthquake resistance, moisture resistance, and environmental friendliness, and is suitable for the following scenarios:
1. Logistics and Transportation Packaging
1. Shock proof and cushioning packaging of electronic products (such as computers and mobile phones), household appliances, glass products, etc. (instead of traditional foam plastics, it is more environmentally friendly).
2. Fill and protect large items such as furniture and ceramics.
2. Home and daily necessities
1. Baby products (such as crawling mats, crash bars, soft and safe).
2. Soundproofing and insulation materials (such as wall and roof filling).
3. Agriculture and Horticulture
1. Packaging and transportation of crops and flowers (moisture-proof and shockproof).
2. Auxiliary materials for thermal insulation greenhouses.
4. Clothing and luggage
1. Clothing lining and shoe material filling (lightweight, breathable).
2. Anti vibration protection for luggage lining.

Lightweight, strong cushioning, earthquake resistant, and environmentally friendly |
Packaging scenarios that require shock absorption, buffering, and moisture resistance (such as transportation of electronic devices, household appliances, and furniture); Home protection (such as baby collision prevention) |
High temperature environment (poor heat resistance) and scenarios requiring high sealing performance |
·Prioritize EVA：
· The material needs to have adhesive properties (such as adhesives), transparency (such as packaging films), or weather resistance (such as photovoltaic modules).
· High requirements for softness and elasticity, such as shoe soles and toys.
·Prioritize EPE：
· The main requirements are shock absorption and cushioning, lightweight and environmentally friendly (such as logistics packaging, baby products).
· It needs to replace traditional foam plastics and is sensitive to cost and environmental protection.
According to the performance requirements of specific usage scenarios, such as strength, heat resistance, and environmental friendliness, two materials can be flexibly selected or combined for use.
