Modified PVA high barrier packaging material

The modified PVA high-barrier packaging material is a new type of material developed by the Aerospace Industry Corporation's 8511 Institute for improved packaging, and has been approved for national patent application. It is now produced by Nanjing Hongbaoli Group Co., Ltd. It is the best product to replace the imported raw materials, production of high barrier packaging materials, also in line with the current national packaging industry policy. A total investment of 10 million yuan, the entire production line manufactured by the domestic production of raw materials, all domestic. The product has the following characteristics: 1 good barrier properties. Oxygen permeability ≤ 1cm3/m2.24h.atm; moisture permeability 3g/m2.24h.2 long storage period, tear strength and puncture resistance. 3 transparency is good. The product has the following characteristics at the same time: 1 Good adhesion, can be coated on PE, PET, BOPA, BOPP, CPP without any pre-coating and adhesive. 2 Without any treatment can modify the PVA surface color printing, ink adhesion is very strong; can also be coated with a layer of modified PVA ink surface, increase brightness. 3 Low heat sealing temperature, excellent resistance to oil and heat sealing. This product mainly has the following varieties: BOPP/modified PVA/PE, BOPA/modified PVA/PE, modified PVA/PE, PET modified PVA/PE, modified PVA/CPP, BOPA/modified PVA/CPP, High-barrier films with special requirements such as PET modified PVA/CPP.
