Abstract
The inner composite film of the packaging bag has certain toughness and impact resistance, and simultaneously has waterproof and air permeability.
Description
Technical Field
The utility model relates to an inner-layer composite film, in particular to an inner-layer composite film for a packaging bag.
Background
Plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, and are used for packaging and as a film coating layer. Plastic packages and plastic package products have a larger share in the market, and particularly, composite plastic flexible packages are widely applied to the fields of food, medicine, chemical industry and the like, wherein the proportion of the plastic packages is the largest, such as beverage packages, quick-frozen food packages, steamed and cooked food packages, fast food packages and the like, and the plastic packages and the plastic package products bring great convenience to the life of people.
The plastic film is one of the essential raw materials for industrial life and social life, the plastic film can be processed into various packaging bag films industrially, and because the quality requirements of the existing packaging bags are higher and higher, the common packaging bags are only provided with one layer of packaging bag film, the function of one layer of packaging bag film is single, the use requirements and the quality requirements of the packaging bags cannot be met at present, and meanwhile, the requirements of the inner layer composite film of the common packaging bag are higher, so that the inner layer composite film of the packaging bag is provided to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing an inner layer composite film for a packaging bag.
The technical problem to be solved by the utility model is realized by adopting the following technical scheme:
an inner layer composite film of a packaging bag comprises a PET film, wherein an aluminizer is bonded on the upper surface of the PET film, an elastic fiber woven layer is bonded on the lower surface of the PET film, a vibration damping buffering bubble layer is bonded below the elastic fiber woven layer, a kraft paper cushion layer is bonded below the vibration damping buffering bubble layer, and a waterproof layer is bonded above the aluminizer;
the waterproof layer is a PE waterproof breathable film;
the aluminizer is formed by compounding a PA material and a PE material;
the utility model has the beneficial effects that: the inner layer composite film of the packaging bag designed by the utility model has certain toughness and impact resistance, and simultaneously has waterproof and air permeability.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
In the figure, 1-PET film, 2-aluminized film, 3-elastic fiber woven layer, 4-vibration damping buffer bubble layer, 5-kraft paper cushion layer and 6-waterproof layer.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the specific drawings.
An inner layer composite film of a packaging bag comprises a PET film 1, an aluminizer 2 is bonded on the upper surface of the PET film 1, an elastic fiber woven layer 3 is bonded on the lower surface of the PET film 1, the PET film 1 enables the packaging bag to have certain toughness, tensile strength and high impact strength, the aluminizer 2 and the elastic fiber woven layer 3 enable the texture of the composite film to be softer in use, and the practicability of the packaging bag is enhanced;
the waterproof layer 6 is a PE waterproof breathable film;
the aluminizer 2 is formed by compounding a PA material and a PE material;
the foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
Claims (2)
