Embodiment 1

[0010] Such as figure 1 As shown, the BOPE peelable film is composed of a subfunctional layer 1, a base layer 2 and a BOPE peelable film adhesive layer 3, and the subfunctional layer 1, the base layer 2 and the BOPE peelable film adhesive layer 3 are thermally bonded together in sequence (the base layer 2 is located at Between the sub-functional layer 1 and the BOPE peelable film adhesive layer 3; the existing co-extrusion process is adopted, and the heat sealing temperature is 60-90° C.).

[0011] The secondary functional layer 1 is formed by mixing polyethylene (PE), slippery agent and antisticking agent, and the mass percentage of each component is: polyethylene (PE) 97%, slippery agent 1%, antisticking agent 2%. The slippery agent is erucamide. The anti-sticking agent is SiO 2 . The function of the secondary functional layer 1 is anti-sticking.

[0012] The base layer 2 is formed by mixing polyethylene (PE) and modified polyethylene (PE), and the mass percentages of e...

Embodiment 2

[0019] It is basically the same as Example 1, except that the antioxidant is 1076 antioxidant (an existing product), and the slippery agent is oleic acid amide.

[0020] Stripping effect is the same as embodiment 1.

Embodiment 3

[0022] Substantially the same as Example 1, the difference is that the antioxidant is 1010 antioxidant (produced as Changzhou Langyi Chemical Co., Ltd.), and the smooth agent is ethylene bis stearamide {(EBS) English Name: Ethylenebis-stearamide Common name: brightener, dispersant, molecular formula: C 38 h 76 N 2 o 2}.

[0023] Stripping effect is the same as embodiment 1.

Abstract

The invention relates to a strippable film, belonging to the technical field of packaging materials. The BOPE (Biaxially Oriented Poly Ethylene) strippable film is characterized by comprising a secondary functional layer, a base layer and a BOPE strippable film rubber layer, and the secondary functional layer, the base layer and the BOPE strippable film rubber layer are thermally bonded together in sequence. The BOPE strippable film rubber layer is prepared from the following component in percentage by mass: 50% of EPDM (Ethylene-Propylene-Diene Monomer) rubber, 35% of paraffin, 10% of polypropylene, 0.1% of antioxidant and 34.9% of ethylene-vinyl acetate copolymer. The film not only can be bonded but also is easy to strip.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a peelable film. Background technique [0002] The existing film adopts a composite layer of glue, and the existing glue has strong adhesion and is generally difficult to peel off. Currently, there is a lack of a film that is both adhesive and easy to peel. Contents of the invention [0003] The object of the present invention is to provide a BOPE peelable film, which can be bonded and easily peeled off. [0004] In order to achieve the above object, the technical solution of the present invention is: a BOPE peelable film, which is characterized in that it consists of a secondary functional layer, a base layer and a BOPE peelable film adhesive layer, and the secondary functional layer, the base layer and the BOPE peelable film adhesive layer are thermally sealed in sequence together. [0005] The BOPE peelable film glue layer is prepared from EPDM glu...
