About multi-layer co-extrusion
Our commonly used meat bags, poultry bags, seafood bags, cheese bags, etc. are basically composite films made of multi-layer films, and then these composite films are used to make packaging bags with different functions.
It has the advantages of concentrating the advantages of a variety of materials, effectively controlling the cost, realizing the adjustment of the film structure according to the needs, and having a wide range of use. Sealing performance, and there is no need for additional compounding during processing, and it does not involve problems such as printing ink, adhesives and auxiliaries. Therefore, it is a relatively green and cost-effective production technology process, which is also very important in PE film manufacturers. common production process.
About High Barrier Technology
High barrier in technical terms refers to very low permeability to low molecular weight chemicals such as gases and organic compounds. High-barrier packaging materials can effectively maintain the original performance of the product and prolong the product life.
Common high barrier materials are polyvinylidene chloride (PVDC), ethylene-vinyl alcohol copolymer (EVOH), polyamide (PA), polyester (PET, PEN)
Tipack prefers PVDC and EVOH as the barrier layer, and achieves high barrier performance through multi-layer co-extrusion technology.At present, Tipack's high-barrier packaging has been launched in more than 100 countries and regions around the world, and has been highly praised by customers. Tipack has passed HACCP, ISO22000 and FDA quality management system certification, and has also passed authoritative quality testing and certification such as Kosher, BRC, and SGS.
