Abstract
The utility model belongs to the technical field of packaging materials and particularly relates to a non-woven fabric aluminum-plastic compound film and a packaging bag. The non-woven fabric aluminum-plastic compound film is of a four-layer structure sequentially comprising a PE (Poly Ethylene) layer, a non-woven fabric layer, an AL (Aluminum) layer and a PET (Polyethylene Terephthalate) layer; a bag body of the packaging bag is provided with a bottom seal and a back seal; the back seal is provided with a back seal strip same as the bag body in length; and the back seal strip is used for connecting two butted sides of the bag body into a whole. The non-woven fabric aluminum-plastic compound film and the packaging bag respectively have a compounded four-layer structure and are good in flexibility, high in strength, good in penetration resistance and capable of packaging products with higher requirements.
Description
Technical field
The utility model belongs to field of packaging material, is specifically related to a kind of nonwoven aluminum-plastic composite membrane and packaging bag.
Background technology
?At present, along with packing, the industrial development of transportation, the packing instructions of product improve constantly, and the packing of product is modernization more and more, and packaging bag is proposed to more and more higher requirement.Existing packaging material generally adopt aluminium-plastic composite structure, but this packaging material can't meet the packing demand to precision equipment.
Summary of the invention
The utility model provides a kind of nonwoven aluminum-plastic composite membrane and packaging bag, can meet the packing of high requirement product.
Technical solutions of the utility model are as follows:
A kind of nonwoven aluminum-plastic composite membrane, is characterized in that, this nonwoven aluminum-plastic composite membrane comprises PE layer, nonwoven layer, AL layer and pet layer four-layer structure successively.
A kind of packaging bag, is characterized in that, this packaging bag comprises bag, and described bag is provided with underseal and back of the body envelope, and back of the body envelope place is provided with a back of the body strip of paper used for sealing suitable with bag length, and described back of the body strip of paper used for sealing connects as one the both sides of bag docking.
Described packaging bag further design is, carries on the back the medial surface that strip of paper used for sealing is located at bag, and back of the body strip of paper used for sealing adopts heat-sealable way to form.
Described packaging bag further design is, carries on the back strip of paper used for sealing and comprises successively PE layer, AL layer and PE layer three-decker.
The beneficial effects of the utility model are:
A kind of nonwoven aluminum-plastic composite membrane of the utility model design, this film has the four-layer structure be combined with each other, and pliability is good, and intensity is high simultaneously, and puncture resistance is good, can meet the packing of the product of high requirement.
The packaging bag of being made by this film is superior performance also.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model nonwoven aluminum-plastic composite membrane.
Fig. 2 is the structural representation of the utility model packaging bag.
In figure: 1-PE layer; The 2-nonwoven layer; The 3-AL layer; The 4-PET layer; 5-carries on the back envelope; The 6-underseal.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
As Fig. 1, shown in 2, the utility model nonwoven aluminum-plastic composite membrane, this composite membrane is provided with four layers, comprise successively PE layer 1, nonwoven layer 2, AL layer 3 and pet layer 4, wherein PE layer 1 is combined into semi-finished product with nonwoven layer 2 by the curtain coating mode, and AL layer 3 and pet layer 4 are combined into semi-finished product by dry type, and the last plastic-aluminum combined semi-finished product of PET are complex as a whole by the curtain coating mode with non-woven fabric compounded semi-finished product again.
The bag of packaging bag of the present utility model is provided with underseal and back of the body envelope, back of the body envelope place is provided with a back of the body strip of paper used for sealing suitable with bag length, this back of the body strip of paper used for sealing connects as one the both sides of bag docking, back of the body strip of paper used for sealing is located at the medial surface of bag, back of the body strip of paper used for sealing adopts heat-sealable way to form, and back of the body strip of paper used for sealing comprises PE layer 1, AL layer 3 and PE layer 1 three-decker successively.
This nonwoven aluminum-plastic composite membrane, and the packaging bag of making has the four-layer structure be combined with each other, pliability is good, and the good intensity of puncture resistance is high simultaneously, can meet the packing of the product of high requirement.
