Bopp pre-coating film environmental performance
BOPP pre-coating film was promoted as the resin coated products, environmental protection is the important reason of its gradually into the mainstream.
EVA as pre-coating film rubber material ( Ethylene - Vinyl acetate copolymer) And contains no bad smell, do not contain heavy metals, do not contain phthalates, biodegradable, rejected or burns will not harm the environment. As a base material bopp ( The two-way stretch polypropylene film) , it is composed of high polymer polypropylene production. Polypropylene is non-toxic, odourless, tasteless and high chemical stability good milk white crystalline polymer. In the cutting process does not produce chemical changes to its, therefore in the process of pre-coating film cutting also won't produce toxic substances.
Old-fashioned solvent-based coating line due to use solvent containing benzene, damage the health of operators and the workshop environment caused great pollution. Pre-coating film laminating process does not produce any harmful substances, without solvent smell, no pollution of the environment. Therefore, pre-coating film laminating process more environmentally friendly.
We have learned, now 80% of China's papermaking fibre source depend on recycling of waste paper, including paper wool, paper edge, etc. In printing, the book covers the use of it is also a huge, if mass type using the tu coated material, can't separate the paper and plastic film, then covered a film of waste paper and paper paper edge, the hair will be unable to recycle, unable to degradation, this will bring inestimable economic loss, is really a waste of resources. And pre-coating film as an environmental friendly technology, paper and membrane separation technology can greatly improve the recovery rate of the paper.
