The invention reside in the structure and type for changing various types of materials, conventional theoretical limitation is particularly breached, from
Jump out, create a kind of both courageously enough using anti-in few wear-resisting and anti-stick circle of both of being compromised with anti-stick additive
Viscous additive, will not grind colored new technology route again.Simultaneously by the adjustment preferably with processing technology of material, it is integrally improved
The anti-swelling effect of thin-film material.The brand-new hard boxization of high-grade Soft Roll is developed by theory innovation and combination practice operation crease-resistant
Wear-resisting cigarette BOPP film, is verified in the navy blue packaging of downstream client, has obtained consumer's approval.
It is emphasized that the core technology scheme of the present invention also needs to accomplish at following 4 points：
1st, from the optimal additive of anti-adhesion effectiveness, wear-resisting type film on the market is solved at present not anti-stick or anti-stick weak
The problem of, and the anti-effect being swelled is played simultaneously；
2nd, from new smooth additive, the smooth composition of liquid has been abandoned in the past, solid-state distribution has been changed to, tries not
Film surface formation lubricating film coat, makes the scuffing object of antiplastering aid particle change or lack；
3rd, from anti-swelling effect good raw material and additive, the generation being swelled is delayed, along with enough special efficacy antiplastering aids
Use, certain air barrier is formed between cigarette-brand paper and film, play collaboration enhancing.
4th, from the various additives of excellent optical performance, it is ensured that will not because of film resting period length excessive infringement light
Performance is learned, the transparency requirement of the soft box of high-grade parcel is met.
Everybody dare not use or can not possibly use the anti-stick composition that the present invention is selected at present, because existing theory thinks
Anti-stick particle is sharply easy to scratch film, is the arch-criminal that film turns white or hazed, and can seriously damage the anti-wear performance of film.
But the state of film surface has been changed in view of the present invention, has even been scratched, has also been some naked eyes None- identifieds
Short and small thin trace, be not in that mill spends the apparent flaws that turn white in flakes afterwards, haze, so can just be used with enough additions.
