Abstract
The utility model relates to a paper-plastic composite packaging material and a packaging bag. The paper-plastic composite packaging material comprises a plastic film layer and a paper layer, and is characterized in that: the joint face of the paper layer is rugged; and plastic is extruded and cast on the joint face of the paper layer to form the plastic film layer. The packaging bag comprises a paper-plastic composite bag body, wherein the inner surface of the bag body is provided with the plastic film layer; the outer surface of the bag body is provided with the paper layer; and matched self-sealing strips are arranged at positions on the two opposite inner surfaces of the bag body close to a bag mouth. Compared with the prior art, the utility model has the advantages that: plastic is molten, extruded and directly cast on the paper layer by using the bonding property and compatibility of molten resin, so that the use of a bonding agent and a chemical solvent is avoided, and environmental friendliness is achieved.
Description
Technical field
The utility model relates to packaging field, specifically refers to a kind of paper plastic combined package material and packaging bag.
Background technology
Along with the raising of manufacturing technology, convenient plastic flexible package use amount attractive in appearance is more and more.Traditional plastic flexible packaging material generally includes the laminated plastics rete, is to bond together by adhesive-layer between the adjacent plastic membranous layer.The employed glue of adhesive-layer need meet 2-4 gram/rice
2Technological requirement, and require coating evenly.Therefore, glue must dilute with ethyl acetate earlier before use, could evenly apply; Utilize the high volatile volatile of ethyl acetate simultaneously, make adhesion agent rapid draing after, two layer materials are pressed together.
But all will all be discharged into contaminated environment in the atmosphere after these solvent evaporates, and as yet the clean residual solvent of volatilization, glue can see through the food the inside that plastic sheeting be moved to packing at leisure, having a strong impact on the safety of food.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, and a kind of paper plastic combined package material that does not comprise adhesive-layer is provided.
Another technical matters to be solved in the utility model provides a kind of paper plastic combined package bag.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the paper plastic combined package material, comprise plastic membranous layer and ply of paper, the face of joint that it is characterized in that described ply of paper is uneven, and Plastic Extrusion is prolonged on the face of joint of described ply of paper and formed plastic membranous layer.
Can also be printed with printed layers on the another side of described ply of paper.
Use the packaging bag of above-mentioned paper plastic combined package material, it is characterized in that comprising the paper and plastics compound bag body, the inside face of this bag is described plastic membranous layer, and the outside face of bag is described ply of paper; Be provided with suitable self-sealed article near the sack position on relative two inside faces of described bag.
Be to be printed with printed layers on the ply of paper on the outside face of described bag.
Described bag is provided with the circular hole that makes things convenient for this packaging bag to collude extension, and this circular hole is positioned at the top of described self-sealed article.
Compared with prior art, the utility model utilizes the adhesive bonding property and the compatibility of molten resin, and plastics are melt extruded the direct curtain coating in back on ply of paper, and two kinds of different materials are bonded together securely, has avoided the use of adhesion agent and chemical industry solvent, environmental friendliness; And have barrier and the heat sealability and the good printing of paper material of plastic sheeting concurrently, it is pollution-free to be used for the packaging for foodstuff sanitation and hygiene, meets the direction of industry of country's green, environmental protection, cleaner production.And the requirement that the article storage is guaranteed the quality has promptly been satisfied in the packaging bag of the prepared self-sealing of material thus, is convenient to remain the preservation of article simultaneously, but and repeated use, help saving.
Composite paper-plastic material provided by the utility model and packaging bag are particularly suitable for packaging for foodstuff.

Fig. 1 is the perspective view of the utility model embodiment;
Fig. 2 is this cutaway view along A-A line among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 2, this paper plastic combined package material comprises:
Ply of paper 1, present embodiment adopts craft paper, and its face of joint is uneven; Can earlier paper be unreeled corona treatment with following plastic membranous layer compound tense, remove the paper surface dust, to increase the peel strength after compound.
Plastic membranous layer 2, present embodiment adopt polyethylene at extruder with vinyon fusion in extruder, curtain coating is extruded from flat die, the polyethylene film of fusion is under the effect of the nip roll of closed contact and cooling stick, infiltrate on the rough ply of paper face of joint, behind the cooling curing, plastic membranous layer 2 promptly is bonded to composite paper-plastic material with ply of paper.
Printed layers 3, the printed layers of on another surface of ply of paper 1, printing various patterns as required.
As shown in Figure 1, above-mentioned composite paper-plastic material is prepared into food pack 3, plastic membranous layer 2 is the inside face of bag 31, and ply of paper 1 is the outside face of bag 31; Be to be printed with printed layers on the ply of paper on the outside face of bag.Be provided with suitable self-sealed article 32 near the sack position on relative two inside faces of bag.The top that is positioned at self-sealed article on the bag is provided with the circular hole 33 that makes things convenient for this packaging bag to collude extension.
Claims (5)
