Characteristics of multi-layer packing film roll
High barrier performance
The use of multi-layer polymers instead of single-layer polymerization can greatly improve the barrier performance of thin films, achieving high barrier effects on oxygen, water, carbon dioxide, odor, and other substances. Especially when using EVOH and PVDC as barrier materials, their oxygen permeability and water vapor permeability are significantly very low.
Strong functionality
Due to the wide selectivity of multi-layer food packing films in material applications, multiple resins can be selected according to the application of the materials used, fully reflecting the functions of different levels, enhancing the functionality of co extruded films, such as oil resistance, moisture resistance, high-temperature cooking resistance, and low-temperature freezing resistance. Can be used for vacuum packaging, sterile packaging, and inflatable packaging.
Low cost
Compared to glass packaging, aluminum foil packaging, and other plastic packaging,plastic film roll has a significant cost advantage in achieving the same barrier effect. For example, to achieve the same barrier effect, seven layer co extruded film has a greater cost advantage than five layer packaging film roll. Due to its simple workmanship, the cost of the produced film products can be reduced by 10-20% compared to dry composite films and other composite films.
Flexible structural design
Adopting different structural designs to meet the quality requirements of different products.
