Abstract
The invention relates to an easily-stripped film, which is formed by extruding three layers of thin films, namely, a composite layer, an intermediate layer and a heat-seal layer. The composite layer comprises the following components in percentage by weight: 65 percent of polyethylene (Q281) and 35 percent of polyethylene (2420H); the intermediate layer comprises the following components in percentage by weight: 50 percent of polyethylene (2426H) and 50 percent of polyethylene (2420H); and the heat-seal layer comprises the following components in percentage by weight: 65 percent of polyethylene (Q281), 20 percent of polybutylene (PB-1) and 15 percent of polyethylene (SP1510). The easily-stripped film implemented by adopting the technical scheme can be compounded with biaxially stretched films such as a biaxially oriented polyester film (BOPET), a biaxially oriented nylon film (BOPA) and the like to be produced into an easily-stripped composite film so as to be produced into an easily-stripped packaging bag. In the packaging bag, the seal strength is between 5 and 10 N/25mm; the stripped part can whiten; the stripped surface is smooth and clean; and the seal integrality is high.
Description
Technical field
The present invention relates to a kind of packaging material, relate to a kind of film for packaging of peeling off easily in particular.
Background technology
Has strict demand for medical treatment, used for packing foods bag at present, be that sealing of packaging bag will possess certain intensity, peeling off the position will bleach when peeling off, stripper surface is smoothly clean, have and seal integrality preferably, the packing bag for medical use that adopts common composite membrane to make is easy to generate wire drawing, chip when peeling off, thereby causes the secondary pollution of medicine equipment.
Summary of the invention
Purpose of the present invention is overcoming the prior art shortcoming, provide a kind of have well peel off effect, the stripping portion potential energy enough bleaches when promptly peeling off, stripper surface is smoothly clean, no wire drawing, chip have good sealing-strength and the medical treatment, the used for packing foods film that seal integrality.
The objective of the invention is to be achieved by following technical solution.
A kind of easily-stripped film of the present invention is co-extruded by composite bed, intermediate layer, hot sealing layer three-layer thin-film, and component of each layer and materials proportioning (by weight percentage) are as follows: composite bed, polyethylene (Q281) 65%, polyethylene (2420H) 35%; The intermediate layer, polyethylene (2426H) 50%, polyethylene (2420H) 50%; Hot sealing layer, polyethylene (Q281) 65%, polybutene (PB-1) 20%, polyethylene (SP1510) 15%.
A kind of easily-stripped film that adopts technique scheme to realize can be compound with biaxial stretching films such as BOPET, BOPA, make composite film easy to peel, and then make the easy-stripping type packaging bag, this packaging bag also can be used for the part packaging for foodstuff applicable to the packing of medicine equipment.The sealing-strength of this packaging bag is between 5～10N/25mm, and it is peeled off the position and can bleach, and stripper surface is smoothly clean, has the good integrality of sealing.This easily-stripped film can be made into the stretched film of thickness at 70～220 μ m simultaneously, directly fits with Du Pont Tyvek material behind the plastics sucking moulding, forms and easily peels off package component, changed Tyvek material in such packing must gluing after could and the situation of stretched film applying.
The specific embodiment
Provide embodiments of the invention and manufacturing process and effect below.
A kind of easily-stripped film of the present invention, be co-extruded by composite bed, intermediate layer, hot sealing layer three-layer thin-film, thickness can change with actual demand, now the mould of easily peeling off with 50 μ m is an example, component of each layer and materials proportioning (by weight percentage) are as follows: composite bed 15 μ m, polyethylene (Q281) 65%, polyethylene (2420H) 35%; Intermediate layer 15 μ m, polyethylene (2426H) 50%, polyethylene (2420H) 50%; Hot sealing layer 20 μ m, polyethylene (Q281) 65%, polybutene (PB-1) 20%, polyethylene (SP1510) 15%.
Manufacturing process of the present invention is as follows:
1, technological process:
A. listed plastic pellet mixes fully by proportioning in will filling a prescription;
B. the particle that mixes is added respectively in the corresponding extruder hopper;
C. set extruder temperature respectively by the technological parameter requirement, start extruder, make plastic pellet fully mixing in barrel;
D. adopt rotating die head, the supreme anchor clamps of thin mode pulling that will from die head, extrude;
E. cold foam-stabilizing device is adjusted to required size with the film bubble in adopting;
F. will go up the packaging film feeding of anchor clamps to wrap-up rolling moulding through rotation.
2, technological parameter:
Extruder temperature (℃):
| One district | Two districts | Three districts | Four districts | Five districts | Six districts | Die head temperature | |
| Hot sealing layer | ??155 | ??160 | ??165 | ??175 | ??170 | ??170 | ??185 |
| The intermediate layer | ??155 | ??160 | ??165 | ??175 | ??170 | ??170 | ??180 |
| Composite bed | ??155 | ??160 | ??165 | ??175 | ??170 | ??170 | ??170 |
Blow-up ratio: 4: 1
Can be compound by a kind of easily-stripped film that above-mentioned prescription and technology are made with biaxial stretching films such as BOPET, BOPA, make composite film easy to peel, and then make the easy-stripping type packaging bag, this packaging bag also can be used for the part packaging for foodstuff applicable to the packing of medicine equipment.The sealing-strength of this packaging bag is between 5～10N/25mm, and it is peeled off the position and can bleach, and stripper surface is smoothly clean, has the good integrality of sealing.
Claims (1)
1. an easily-stripped film is co-extruded by composite bed, intermediate layer, hot sealing layer three-layer thin-film, and component of each layer and materials per distribution ratio by weight are as follows: composite bed, polyethylene (Q281) 65%, polyethylene (2420H) 35%; The intermediate layer, polyethylene (2426H) 50%, polyethylene (2420H) 50%; Hot sealing layer, polyethylene (Q281) 65%, polybutene (PB-1) 20%, polyethylene (SP1510) 15%.
