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
The invention belongs to field of packaging material, be specifically related to a kind of peelable film.
Background technology
Existing film adopts compound one deck glue, and the cementability of existing glue is stronger, generally is difficult to peel off.At present, lack a kind of film that can bondingly easily peel off again.
Summary of the invention
The object of the present invention is to provide a kind of BOPE peelable film, this film can bondingly easily be peeled off again.
To achieve these goals, technical scheme of the present invention is: the BOPE peelable film, it is characterized in that it is made up of subfunction layer, basic unit and BOPE peelable film glue-line, and subfunction layer, basic unit and BOPE peelable film glue-line heat seal successively are in the same place.
Described BOPE peelable film glue-line is formed by ethylene-propylene diene copolymer, paraffin wax, polypropylene, oxidation inhibitor, ethene-vinyl acetate copolymer, and the shared mass percent of each component is: ethylene-propylene diene copolymer 50%, paraffin wax 5%, polyethylene 10%, oxidation inhibitor 0.1%, ethene-vinyl acetate multipolymer 34.9%.
The invention has the beneficial effects as follows: owing to adopted BOPE peelable film glue, this glue can bondingly easily be peeled off again, thereby this film can bondingly easily be peeled off again.
Description of drawings
Fig. 1 is the structural representation of BOPE peelable film of the present invention;
Among the figure: 1-subfunction layer, 2-basic unit, 3-BOPE peelable film glue-line.
Embodiment
Embodiment 1:
As shown in Figure 1, the BOPE peelable film, it is made up of subfunction layer 1, basic unit 2 and BOPE peelable film glue-line 3, subfunction layer 1, basic unit 2 and BOPE peelable film glue-line 3 successively heat seal (basic unit 2 is between subfunction layer 1 and BOPE peelable film glue-line 3 together; Adopt existing coextrusion process, 60~90 ℃ of heat-seal temperatures).
Described subfunction layer 1 is mixed by polyethylene (PE), slipping agent and release agent, and the shared mass percent of each component is: polyethylene (PE) 97%, slipping agent 1%, release agent 2%.Described slipping agent is an erucicamide.Described release agent is SiO
2The effect of subfunction layer 1 is antiseized.
Described basic unit 2 is mixed by polyethylene (PE) and modified poly ethylene (PE), and the shared mass percent of each component is: polyethylene (PE) 98%, modified poly ethylene (PE) 2%.
Described BOPE peelable film glue-line is prepared from by ethylene-propylene diene copolymer (EPDM), paraffin wax, polyethylene (PE), oxidation inhibitor, ethene-vinyl acetate multipolymer (EVA), and the shared mass percent of each component is: ethylene-propylene diene copolymer 50%, paraffin wax 5%, polyethylene 10%, oxidation inhibitor 0.1%, ethene-vinyl acetate multipolymer 34.9%.Described oxidation inhibitor is phosphite.The raw material of apolegamy is mixed, be processed into particulate state (extrusion temperature is 160~200 ℃), obtain BOPE peelable film glue-line by forcing machine.
The material of BOPE peelable film glue-line: the material of basic unit: the mass ratio of the material of subfunction layer is 1: 1: 1.
The preparation method of BOPE peelable film is: the extrusion temperature of basic unit 2, BOPE peelable film glue-line 3 is 160~200 ℃, and the extrusion temperature of subfunction layer 1 is 160~220 ℃.The raw material of apolegamy is sent into forcing machine be processed into melt, melt becomes sheet by curtain coating casting sheet co-extrusion; Adopt existing coextrusion process, 60~90 ℃ of heat-seal temperatures.
The BOPE peelable film that BOPE peelable film glue of the present invention is arranged is peeled off experiment: peel off the BOPE peelable film with the heat-sealing tensiometer, peeling off pulling force in the time of 85 ℃ is 0.2~0.6 newton, promptly easily peels off; Illustrate that the present invention can bondingly easily peel off again.
Under the similarity condition, and adopt existing heat-sensitive glue to peel off experiment, peeling off pulling force is 10 newton, and existing cementability is stronger, generally is difficult to peel off.
Embodiment 2:
Substantially the same manner as Example 1, difference is: described antioxidant is 1076 antioxidants (for currently available products), and described slipping agent is an amine hydroxybenzene.
Peel off effect with embodiment 1.
Embodiment 3:
Substantially the same manner as Example 1, difference is: described antioxidant is 1010 antioxidants (producing as the bright ease chemical in Changzhou company limited), described slipping agent is that { (EBS) English name: Ethylenebis-stearamide is commonly called as ethylene bis stearamide: brightening agent, dispersion agent, molecular formula: C
38H
76N
2O
2.
Peel off effect with embodiment 1.
The present invention cited each raw material (comprising different molecular weight, different manufacturers) can both be realized the present invention, does not enumerate embodiment one by one at this.
