Barrier Cast Film Line
- Raw materials PE, PP, PA, EVOH
- Film weight range 0.02-0.20mm
- Net film width From 1200mm to 3000mm
- Film layer structure 5-layer, 7-layer or 9-layer
The PE perforated film is used as the top sheet of sanitary napkin, baby diaper; food packaging such as butter wrapping, meat absorbent pad, and agricultural application.
Our multi-layer cast film line is capable of producing high quality barrier film by combining resins PE, PP, PA, and EVOH with 5 or 7 layers film structure. The barrier film line uses automatic T die with edge encapsulation technology for cost-efficiency, which allow the recycling of edge trim. Besides barrier film, the line is versatile for producing CPP film and CPE film, which create great flexibility for you.
EVOH high-barrier film is one of the most widely used high-barrier materials. There are also heat-resistant types for aseptic packaging products. The barrier properties of EVOH high barrier films depend on the ethylene content. Generally speaking, when the ethylene content increases, the gas barrier properties decrease, but it is easy to process.
In the field of packaging, EVOH is made into a composite film intermediate barrier, which is used in all rigid and flexible packaging; in the food industry, it is used in aseptic packaging, hot cans and retort bags, packaging dairy products, meat, juice cans and Condiments; in non-food, it is used for packaging solvents, pesticide chemicals, air-conditioning structural parts, gasoline barrel linings, electronic components, etc.
In terms of food packaging, EVOH's plastic containers can replace glass and metal containers. Many domestic aquatic companies use PE/EVOH/PA/RVOH/PE five-layer co-extrusion film vacuum packaging for exporting seafood. While accelerating the research of EVOH composite film, the stretching orientation of EVOH high-barrier film is also being studied abroad. The gas barrier performance of the new EVOH film is 3 times that of the existing high-performance non-stretch EVOH film.
