Abstract
The utility model discloses a food package composite film comprising a printing layer, a separation layer, a secondary inner layer and a thermal sealing layer in sequence from top to bottom, wherein the adjacent layers are adhered through an adhesive; and the thermal sealing layer is an organic silicon polyethylene thin film. The food package composite film provided by the utility model has the advantages in that the food package composite film is formed by compositing four layers of materials, so that the composite film has very high strength and good separation property, and the food package composite film provides a longer guarantee period for a package product; and meanwhile, the food package composite film uses polydimethylsiloxane as a slipping agent of the composite film, so that a friction coefficient of the composite film is accurately and stably controlled, particularly, the food package composite film has more advantages when being compared with the composite film using an ordinary inorganic slipping agent in an automatic packaging process.
Description
Technical field
The utility model relates to a kind of packaging composite film, specifically, relates to a kind of food packing composite film.
Background technology
Food security is the hot issue that consumers in general are concerned about, large quantities of problem food have appearred on the market, malicious coffee that exceeds standard such as plasticiser beverage, melamine milk powder, mould etc., except some illegal retailers abused additive, the performance of packaging material for food also directly affected food sanitation safe.The outstanding packaging material of for this reason producing high strength, high-barrier are important topics that flexible package enterprise faces.Many these based packaging materials have also appearred on the market in recent years.But these flexible packing materials mostly still adopt traditional inorganic matter as main slipping agent composition, and such as oleamide, erucyl amide etc., these material costs are cheap, and are respond well and be widely adopted.But because inorganic slipping agent adopts the mode of separating out to come composite lubricating film, and the difficult control of this process, the amount of separating out of slipping agent is often bigger than normal or less than normal, the phenomenon that " skidding " in some processes of automatically packing, can occur, increase thus the control difficulty of the packing of product, wasting phenomenon occurred easily.
The utility model content
The purpose of this utility model is to provide a kind of food packing composite film, can effectively solve existing food-film and automatically can occur skidding in the packaging process, increases the wasting problem of control difficulty of the packing of product.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of food packing composite film, comprise successively printed layers, barrier layer, inferior internal layer, hot sealing layer from top to bottom, by polymer adhesive, described hot sealing layer is the organosilicon polyethylene film between the described adjacent layer.
Preferably, described printed layers is biaxially oriented polyester film or two-way stretching polyamide film; Good printing effect can be arranged.
Preferably, described barrier layer is aluminium foil layer; Have preferably barriering effect, it is expired to guarantee that food is difficult for.
Preferably, described internal layer is biaxially oriented polyester film or two-way stretching polyamide film; Resistance to tension is strong.
Preferably, described bonding agent is dry type compound polyurethane adhesive or solvent-free composite polyurethane adhesive; The bonding firm while can not separated out contaminated food products.
Compared with prior art, the utility model has the advantages that: be composited with four layer materials, make composite membrane have very high intensity, therefore excellent barrier property can give packaging product the long shelf-life; Adopt simultaneously the slipping agent of dimethyl silicone polymer as composite membrane, made the composite membrane coefficient of friction precise and stable controlled, especially automatically adopted the composite membrane of common inorganic slipping agent that greater advantage is arranged in the packaging process.
Description of drawings
Fig. 1 is the structural representation of a kind of food packing composite film of the utility model.
The specific embodiment
Consult the embodiment that Fig. 1 is a kind of food packing composite film of the utility model, a kind of food packing composite film, comprise successively printed layers 1 from top to bottom, barrier layer 2, inferior internal layer 3, hot sealing layer 4, pass through polymer adhesive between the described adjacent layer, described hot sealing layer 4 is the organosilicon polyethylene film, be evenly distributed with molecular weight in the described hot sealing layer 4 and surpass 500,000 dimethyl silicone polymer organosilicon, described printed layers 1 is biaxially oriented polyester film or two-way stretching polyamide film, described barrier layer 2 is aluminium foil layer, described time internal layer 3 is biaxially oriented polyester film or two-way stretching polyamide film, and described bonding agent is dry type compound polyurethane adhesive or solvent-free composite polyurethane adhesive.
Described organosilicon polyethylene film is the inner evenly organosilyl modified poly ethylene film of distribution dimethyl silicone polymer, be composited with four layer materials, make composite membrane have very high intensity, therefore excellent barrier property can give packaging product the long shelf-life; Adopt simultaneously the slipping agent of dimethyl silicone polymer as composite membrane, made the composite membrane coefficient of friction precise and stable controlled, especially automatically adopted the composite membrane of common inorganic slipping agent that greater advantage is arranged in the packaging process.
The above only is specific embodiment of the utility model, but technical characterictic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
