Description
Technical Field
The utility model relates to a stretch film technical field specifically is an imitative aluminium foil stretch film.
Background
The stretching film is a transparent, flexible and harmless polyethylene plastic film with high elasticity and strength, is nontoxic and harmless, meets the international environmental protection and sanitation standards, has the advantages of toughness, impact resistance and transparency, can prevent moisture and dust, reduce labor and improve benefit no matter used for collective packaging of products or cargo clamping plates, and achieves the purposes of protecting the products and reducing cost;
the existing stretch film is usually of a transparent structure and single in structure, cannot meet the requirement of individualized packaging of part of requirements, meanwhile, the puncture resistance and toughness of the stretch film are not ideal, and the stretch film is damaged due to over-stretching, so that the protection effect is lost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an imitative aluminium foil tensile membrane, it is strong to have puncture resistance, makes tensile membrane be difficult for the damage, and increase of service life has superstrong winding power and returns the elasticity of contracting, is convenient for firmly tie up the packing, and can satisfy the individualized packing of part requirement, characteristics that the practicality is stronger.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an imitative aluminium foil stretch film, includes first tensile membrane, the upper and lower both sides of first tensile membrane are all laminated and are connected with the tensile membrane of second, two one side that the tensile membrane of second carried on the back mutually all is provided with the aluminized layer.
In order to improve the tensile strength and puncture resistance of the whole stretched film, the aluminum foil-like stretched film of the present invention is preferably the first stretched film which is linear low-density polyethylene.
For the winding force and the retractility of the stretch film, the second stretch film is a PET shrink film as the utility model discloses an aluminum foil-imitated stretch film is preferable.
Make it be difficult for droing in order to stretch the viscidity between membrane and the article, conduct the utility model discloses an imitative aluminium foil stretch membrane is preferred, is located the lower terminal surface laminating of below aluminizing layer and is connected with the viscose membrane.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the aluminum foil-imitated stretching film is formed by taking linear low-density polyethylene as a middle layer, taking a PET (polyethylene terephthalate) shrink film as an inner layer and an outer layer and extruding and pressing the PET shrink film through plasticization, wherein the first stretch film is made of linear low-density polyethylene and has high strength, high toughness, high rigidity, heat resistance, high cold resistance, high environmental stress cracking resistance, high impact strength, high tear strength and other properties, so that the puncture resistance of the whole stretch film is improved, the stretch film is not easy to damage, the service life is prolonged, the second stretch film is made of the PET shrink film and has super-strong winding force and retraction property, the packaging can be firmly bound, aluminum-plated layers are arranged on two opposite sides of the two second stretch films, the silver-imitating effect of an aluminum foil is formed, the whole stretch film achieves the attractive effect after the silver-imitated effect is achieved, the individualized packaging can be met, the practicability is higher, and the adhesiveness between the stretch film and an article is increased through the arrangement of an aluminum-plated adhesive film, so that the stretch film is not easy to fall off.
