Abstract
The food packing composite film includes at least one printed plastic film layer, one aluminum plated heat sealing layer and one adhesive layer to adhere the printed plastic film layer and the aluminum plated heat sealing layer into one integral structure. The adhesive layer may be of common glue or special glue for aluminum plated layer, and the compounding mode may be a dry one, a wet one or no-solvent one. The composite film product has ply separation resistance not lower than 0.8 N/ sq m and heat sealing strength not lower than 1 N/sq m, and is cut and further made into required packing bag. The present invention has the advantages of certain metal texture, certain transparent degree for showing packed matter and excellent obstructing function to oxygen and water vapor.
Description
Technical field
The present invention relates to a kind of food packing composite film, the invention still further relates to the manufacture method of this food packing composite film.
Background technology
Food in the market, use the comparatively of composite film packaging to see more, except aluminium foil layer is arranged, the complex film of paper layer, remaining can be divided into non-aluminized complex film and aluminized complex film, non-aluminized complex film has certain bandwagon effect to content, aluminized complex film then is to adopt metallized film at interlayer or internal layer, improved the metal-like of whole packing, but the packing material bandwagon effect that does not possess non-aluminized complex film, to the barriering effect of oxygen and water vapour is that with the non-aluminizer of spline structure tens times are to hundreds of times, for some instant packagings for foodstuff, its barriering effect does not find full expression, be actually a kind of waste, promptly excessive packaging causes the waste of cost and resource, increases difficulty for simultaneously raw-material recycling.For common aluminized products, its compound tense generally must adopt specific glue special, and price is higher.
Summary of the invention
The object of the present invention is to provide a kind of with low costly, have the food packing composite film of certain presentation effect and metal-like.The present invention also provides the manufacture method of this food packing composite film simultaneously.
For achieving the above object, the present invention can take following technical proposals:
Food packing composite film of the present invention comprises the complex film body, it is characterized in that: described complex film body comprises at least one plastics undertake the printing of layer, adhesive layer and the hot sealing layer of aluminizing.
Described plastics undertake the printing of the layer and aluminize hot sealing layer bonding by adhesive layer be an integral structure.
Described plastics are undertaken the printing of layer for having the plastic layer of good transparency.
The described hot sealing layer of aluminizing is to have the necessarily heat sealable polyethylene or the cast polypropylene film of the amount of aluminizing, and its optical density (OD) is between 0.2--0.8.
The described plastics layer thickness of undertaking the printing of is 8--100 μ m, and the thickness of the described hot sealing layer of aluminizing is 15--80 μ m.
Described adhesive layer is the common glue layer or the special glue water layer of aluminizing.
The manufacture method of food packing composite film of the present invention is: is integral structure with undertake the printing of layer and the hot sealing layer of aluminizing of the plastics that print by the compound slaking of adhesive layer, wherein adhesion agent can adopt the common glue or the glue special of aluminizing, complex method comprises dry type, wet type, solvent-free complex method, forms interlaminar strength 〉=0.8N/m after compound slaking
2, heat seal strength 〉=1N/m
2The complex film finished product, through cut, bag makes needed packaging film and gets final product.
The invention has the advantages that and adopt special straticulate structure and the material of this kind, simplified the aluminum plating process process of the hot sealing layer of aluminizing, compound tense is not limited to adopt the glue special of aluminizing, and can adopt multiple complex method simultaneously, and therefore the food package film of making is with low cost.After compound slaking moulding, the finished product complex film had both had metal-like, had certain perspectivity again, had satisfied to the display function of packing material with to the barriers function of oxygen and water vapour.The packaging film that the present invention in addition protected is convenient the recovery after use, is beneficial to environmental protection, for instant noodles, biscuit etc. fast the packing of consumer food a kind of new method is provided.
