Abstract

The utility model discloses a self-adhesion protective film, which comprises a low-density print layer, a high-density separation layer and an elastic body self-adhesion layer which are sequentially arranged. The outer surface of the low-density print layer can be printed with texts. The middle high-density separation layer can effectively prevent permeation of the print layer, thereby keeping attractive appearances of products and improving quality of products. The elastic body self-adhesion layer enables the whole film to be free from extraneous odor and good in stability. The film can be tore down without adding various accessory ingredients at high temperature, thereby being low in cost and good in transparency. When the self-adhesion protective film is adhered to surfaces of plate materials, surfaces of plate materials can be effectively prevented from being damaged.

Description

A kind of adhesive protecting film

[technical field]

The utility model relates to adhesive protecting film, relates in particular to the adhesive protecting film that is pasted on polycarbonate (PC) plate, the acrylic sheet materials such as (PMMA).

[background technology]

Protective membrane be widely used in various product store and the process of transportation in, with avoid product contaminated, scratch, cause problem such as scratch.Protective membrane covers the surface of polycarbonate (PC) sheet material, acrylic (PMMA) sheet material, PS (PS) sheet material, Vestolen PP 7052 (PP) sheet material, can in storage, transportation and construction process, shield.

Present protective membrane printed layers is prone to infiltration, influence outward appearance and use, and film has peculiar smell, and poor stability, the cost height.

[utility model content]

The purpose of the utility model solves the problems of the prior art exactly, proposes a kind of adhesive protecting film, can avoid printed layers to be prone to the problem of infiltration, promotes product quality, and eliminates the film peculiar smell, improves stability, reduces cost.

For realizing above-mentioned purpose, the utility model provides a kind of adhesive protecting film, comprise the low density printed layers, high-density barrier layer, the elastomerics self-adhesive layer that set gradually, but the outside surface printing word of said low density printed layers.

As preferably, said low density printed layers is the new LDPE (film grade) printed layers, and the high-density barrier layer is the high density polyethylene(HDPE) barrier layer, and the density of high density polyethylene(HDPE) barrier layer is higher than the density of new LDPE (film grade) printed layers.

As preferably, said elastomerics self-adhesive layer is propylene-based elastomeric self-adhesive layer or polyolefin elastomer self-adhesive layer or red shortness's elastomerics self-adhesive layer or polyene elastomerics self-adhesive layer.

As preferably, the thickness of said low density printed layers is the 20-40% of total thickness, and the thickness of high-density barrier layer is the 20-40% of total thickness, and the thickness of elastomerics self-adhesive layer is the 20-40% of total thickness; Require and in this scope, to regulate according to Different products layer thickness.

The beneficial effect of the utility model: the utility model intermediary high-density barrier layer can effectively stop the infiltration of printed layers, has kept the good appearance of product, has improved product quality; Adopt the elastomerics self-adhesive layer, whole film free from extraneous odour, good stability; Need not add each analog assistant, tear it down easily during high temperature yet, lower than original cost; The transparency is good, sticks on plate surface to it, can prevent effectively that the surface of sheet material from sustaining damage.

Characteristic of the utility model and advantage will combine accompanying drawing to be elaborated through embodiment.

[description of drawings]

Fig. 1 is the structural representation of a kind of adhesive protecting film of the utility model.

[embodiment]

As shown in Figure 1, adhesive protecting film comprises the low density printed layers 2, high-density barrier layer 3, the elastomerics self-adhesive layer 4 that set gradually, but the outside surface printing word 1 of said low density printed layers 2.Said low density printed layers 2 is the new LDPE (film grade) printed layers, and high-density barrier layer 3 is the high density polyethylene(HDPE) barrier layer, and the density of high density polyethylene(HDPE) barrier layer is higher than the density of new LDPE (film grade) printed layers.Said elastomerics self-adhesive layer 4 is propylene-based elastomeric self-adhesive layer (POP) or polyolefin elastomer self-adhesive layer (POE) or red shortness's elastomerics self-adhesive layer (POE) or polyene elastomerics self-adhesive layer (POE).Elastomerics self-adhesive layer 4 can adopt POP or POE and PE to mix, its body branch:

A. low sticking: 15-25%POP (or POE)/75-85%PE

B. sticking in: 25-35%POP (or POE)/65-75%PE

C. high sticking: 35-45%POP (or POE)/55-65%PE

D. extra-high-speed is sticking: the following PE of 45% above POP (or POE)/55%

The thickness of said low density printed layers 2 is 20-40%, and the thickness of high-density barrier layer 3 is 20-40%, and the thickness of elastomerics self-adhesive layer 4 is 20-40%; Require and in this scope, to regulate according to Different products layer thickness.

This adhesive protecting film can adopt three-layer co-extruded blown film method or three layers of casting method to process.Outer field new LDPE (film grade) printed layers (LDPE) has excellent film-forming properties, and is convenient to printing word.The high-crystallinity of high density polyethylene(HDPE) barrier layer (HDPE) has caused its high-density, tension stress intensity, and the high temperature torsion temperature, viscosity and chemicalstability, it has stronger permeability resistance than LDPE, can avoid the infiltration of printing word.General density is higher than 0.91g/cm ³Be called high density polyethylene(HDPE), be lower than 0.91g/cm ³Be called new LDPE (film grade).

The foregoing description is the explanation to the utility model, is not the qualification to the utility model, any protection domain that scheme after the utility model simple transformation is all belonged to the utility model.
