Description
Technical field
The utility model relates to a kind of packing technique field, be specifically related to a kind of can laser coding easily tear packaging film and packaging bag.
Background technology
Packaging bag is the protective as content, plays effects such as taking up article, marking articles, sealing article.Wherein, the function main source of marking object has: the design, bag shape style, identification code etc. on packaging bag surface.Identification code can be word, figure, image, bar code, Quick Response Code, product production line number etc.
For Biscuit Wrapping Bag, conventional Biscuit Wrapping Bag itself adopts Biaxially oriented polypropylene (BOPP) and cast polypropylene (CPP) two layer composite structure.Wherein, CPP mainly plays the effect of heat-sealing, and BOPP plays provides intensity and the effect as ink printing base material.The packaging bag of this structure of composite membrane uses producer can only carry out printing coding in the side that BOPP or CPP is exposed, the mark code namely printed composite membrane outer surface, be buyer or user's finding, or composite membrane inner surface, contact with content; The former do not conform to be suitable for printing containing sales promotion, preferential etc. do not wish the visible identification code of consumer, and easily altered by illegal businessman, the latter can bring potential impact to product safety.
Except printing coding, also have some by laser code spraying technology, it is by laser at article surface transient evaporation, need not ink consumptive material, easy to maintenance, be convenient to identify, generation be a kind of permanent identifier that cannot wipe.This code spraying technology requires that in composite membrane, arrange at least one deck can stop the barrier layer of laser or infrared light, as aluminium foil or evaporation aluminium lamination, thus forms identification code in the side on barrier layer.Such as common aluminum polyester and heat-sealing film just can be used for laser coding by the gluing composite membrane obtained of glue layer, can form identification code.But guidance quality difference is torn in the packaging bag that its shortcoming is composite membrane to be made, often need repeatedly to tear the opening that could be formed and can enough make content be removed.
Summary of the invention
The purpose of this utility model be to design a kind of can be used for laser coding easily tear packaging film and packaging bag.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of can laser coding easily tear packaging film, this easily tears packaging film is multilayer complex films, and multilayer complex films comprises biaxially oriented polypropylene film, outer glue layer, Biaxially oriented polypropylene aluminizer, interior glue layer and cast polypropylene film from outside to inside successively.
With existing can compared with the packaging film of laser coding, the utility model
The utility model packaging film by Biaxially oriented polypropylene aluminizer and biaxially oriented polypropylene film gluing with the deflection ensureing packaging bag and intensity, and both have and good tear guidance quality, thus packaging film and packaging bag are easily torn, through a tearing notch and peelable packaging bag, easy to use.In addition, the aluminium coated in Biaxially oriented polypropylene aluminizer has good resistance photosensitiveness, and packaging film from inner side laser coding, can be improved the disguise of coding, and can not produce harmful effect to food security.The thickness of described biaxially oriented polypropylene film is 12-15 micron.
The thickness of described Biaxially oriented polypropylene aluminizer is 10-12 micron.
The thickness of described cast polypropylene film is 20-30 micron.
In order to improve easy-to-rupture, preferably, the thickness of described biaxially oriented polypropylene film is 12 microns; The thickness of described Biaxially oriented polypropylene aluminizer is 10 microns; The thickness of described cast polypropylene film is 20 microns.
In order to improve packaging film deflection, preferably, described Biaxially oriented polypropylene aluminizer comprises Biaxially oriented polypropylene basic unit and aluminium coated, and aluminium coated is towards described cast polypropylene film.
In order to improve the fastness of printing-ink, preferably, the inner surface of described biaxially oriented polypropylene film is also printed with ink layer.
In order to improve the disguise of identification code, preferably, described cast polypropylene film and described interior glue layer local laser etching form identification code.
The present invention also comprises containing above-mentioned packaging bag of easily tearing packaging film.
Preferably, described packaging bag is also provided with pre-tearing notch, and one of them draw direction of one of them draw direction of described biaxially oriented polypropylene film and described Biaxially oriented polypropylene aluminizer is parallel to the bearing of trend of pre-tearing notch.
Advantage of the present utility model and beneficial effect are: the utility model packaging film and packaging bag can inner laser codings, and not only coding is hidden, and coding can not produce content and pollutes; The more important thing is, this packaging bag easy-to-rupture is good, is suitable as the packagings for foodstuff such as biscuit, and a tearing notch and peelable packaging bag are easy to use.
