Description
Technical field
The present invention relates to composite soft packaging and the production technical field of label printing industry, more particularly to a kind of medicine and food
Product are packed for BOPP metallized films and preparation method thereof.
Background technology
At present, film base material of being aluminized in the market composite soft packaging and label printing industry often chooses PET (poly terephthalic acids
Glycol ester) and BOPP (bidirectional stretching polypropylene film).Wherein, BOPP has light, inexpensive, nontoxic, moistureproof, printing performance
Well, mist degree is low and decorates the advantages that functional and attention.High-barrier type BOPP base material metallized films are polypropylene films
The high-end product of middle newer type, at present China energy higher to performance requirements such as barrier, adhesive strength of aluminizing, heat-seal strengths
It is few to produce the enterprise of this product, and then larger to its demand both at home and abroad, domestic substantial amounts of high-barrier type BOPP base materials plating
The demand almost all of aluminium film relies on import to meet.
In the market extensively production and application BOPP aluminizers, be that conventional BOPP is process through aluminizing, but its plate
Aluminium lamination fastness with 3M-610 adhesive tapes avulsion detection thing can only achieve it is 85%~90% not de- (i.e. avulsion dealuminzation rate up to 10%~
15%) (3M-610 adhesive tapes are to meet national sector standard to level：Be packed in metallized film BB/T0030-2004
6.12.1 the transparent BOPP pressure-sensitive tapes that peel strength is 2.0N/cm in bar), also it is not reaching to composite flexible pouch and label
Peel strength between internal layer and secondary internal layer after requirement of the printing industry to BOPP aluminizers, i.e. polyester aluminizer and other materials are compound
>=1.0N/15mm (national pharmaceuticals industry standards：4.4th article of regulation in composite membrane for packaging medicine YY0236-1996) water
It is flat to differ greatly.After BOPP aluminizers and other materials common at present is compound, aluminium coated and time outer interlaminar strength are basic
On all≤0.5N/15mm so that BOPP aluminizers purposes and use range are extremely limited.
The content of the invention
The technical problems to be solved by the invention are to overcome existing BOPP aluminizers to be difficult to reach composite flexible pouch
And requirement of the label printing industry to BOPP aluminizers, aluminium coated are substantially all≤0.5N/15mm with time outer interlaminar strength,
It is far apart with national pharmaceuticals industry standard YY0236-1996, the defects of medicine and packaging for foodstuff etc. can not be applied to, there is provided one
Kind medicine and food packaging BOPP metallized films and preparation method thereof.The medicine and food packaging BOPP of the present invention is aluminized thin
Film has excellent barrier property, aluminium lamination attachment fastness height and even compact, good stability of the dimension, the coefficient of friction in non-face of aluminizing
It is small, and the medicine of the present invention and food packaging BOPP metallized films have low envelope temperature and high heat-sealing strength, can be used for
The packaging material in the fields such as food and medicine with high-barrier packing instructions.The medicine of the present invention and food packaging BOPP platings
The medicine of excellent quality can be made by selection and the optimization of processing technology to raw material and formula in the preparation method of aluminium film
Product and food packaging BOPP metallized films, client is disclosure satisfy that to shallow reticulated printing adaptability and the particular/special requirement of combination process,
Printing, compound rear barrier are substantially unattenuated, and the preparation method is produced in batches suitable for industrialization.
The present invention solves above-mentioned technical problem by the following technical programs.
