The physical properties of PEVA film are superior to many traditional plastics, especially flexibility and impact resistance. Due to the addition of EVA ingredients, PEVA is more flexible than ordinary PE film and can provide better cushioning protection, so it is very suitable for packaging fragile items such as electronic products, glass products, etc. In addition, PEVA film has stronger tear resistance and puncture resistance, which can effectively reduce the packaging breakage rate during transportation and warehousing, thereby reducing logistics costs.
PEVA film exhibits excellent heat sealing performance and processing adaptability during packaging production. Due to the addition of EVA, PEVA film can achieve heat sealing at a lower temperature, which not only improves packaging efficiency but also reduces energy consumption. In addition, PEVA film has high surface flatness, is easy to compound with other materials, and can be printed with high precision, so it is widely used in high-end packaging fields such as cosmetics, electronic products, etc.
The transparency and glossiness of PEVA film can be adjusted according to demand, making it more flexible in packaging design. The transparency of standard PEVA film is close to that of ordinary PE, but by adjusting the EVA content or adding special additives, it can be made into a matte or matte effect to meet the visual needs of different products. For example, silver-gray EVA industrial film not only has a unique color, but also provides UV protection or light-shielding properties, which is suitable for special scenarios such as photosensitive materials and pharmaceutical packaging.
PEVA film can still maintain good flexibility in low-temperature environments, which is an advantage that many traditional plastics (such as ordinary PE) cannot match. In low-temperature application scenarios such as frozen food packaging and cold chain logistics, PEVA film is not easy to become brittle and can ensure the integrity and functionality of the packaging. This feature makes it an ideal choice for frozen food bags, ice bags, refrigerated transportation packaging and other fields.
PEVA film has a lower density, which enables lighter and thinner packaging design, thereby reducing the use of raw materials and reducing costs. Although the unit price of PEVA may be slightly higher than that of ordinary PE film, its comprehensive performance (such as reducing breakage rate and improving packaging efficiency) can significantly reduce the overall packaging cost. In addition, the recyclability of PEVA is also in line with the sustainable development strategy of modern enterprises, which helps to enhance the brand image and meet environmental regulations.
