Abstract
The invention discloses a film easy to uncover and an application method of the film. The film easy to uncover is used for sealing a container and consists of a three-layer structure, namely an inner layer, a middle layer and an outer layer, and the inner layer is bonded with a seal; each layer is made of a macromolecular polymer material; the film uneasy to uncover is used for sealing the container in steps of bonding, sealing and the like. The film easy to uncover and the application method of the film have advantages of proneness in uncovering, sanitation, safety, high sealing efficiency, wide application range and the like.
Description
Technical field
The present invention relates to a kind of film, particularly relate to a kind of film for container closure.
Background technology
Current Guiling Jelly, the article such as Yoghourt, cutlery box, in order to fresh-keeping or prevent smell from volatilizing, all need to use diaphragm seal in the sealing of container, current sealed membrane has following shortcoming: first, not easily open, maybe need need to be torn rotten by very large power by cutter, the easy splash of such content out pollution clothes there is potential safety hazard; The second, thermal viscosity is poor, and heat-seal speed is slow, affects packaging efficiency.
Summary of the invention
The present invention is intended to solve above-mentioned mentioned technical problem, provide a kind of and easily open, clean hygiene and packaging efficiency high easily take off epiphragma and using method thereof.
The present invention is realized by following technical scheme:
One easily takes off epiphragma, is combined into by three floor height Molecularly Imprinted Polymers, and bonding with the sealing of container is internal layer, and all the other are two-layer is middle level and skin; Described internal layer is polybutene copolymer or ethene improved-acrylic materials, and described middle level is the mixture of low density polyethylene (LDPE) and metallocene low density polyethylene (LDPE), and described skin is the mixture of low density polyethylene (LDPE) and metallocene low density polyethylene (LDPE).
Further, the thickness proportion of described skin, middle level and internal layer is 3:4:3.
Easily take off a using method for epiphragma, it comprises the steps:
Extrusion process is used to be bonded by the lid of the described skin and container of easily taking off epiphragma;
According to the size of sealing, lid described in cutting;
By heat-seal technique, in the sealing internal layer of described lid being adhered to container and airtight container.
Further, describedly epiphragma is positioned at same plane sealing for encapsulating profile is easily taken off.
Beneficial effect is: one of the present invention easily takes off epiphragma, and the easier sealing from container is opened, sealing on, noresidue without wire drawing, clean hygiene; Simultaneously due to excellent thermal viscosity, packing producing line can be encapsulated faster, improve the operating efficiency of packaging line, reduce packing cost; Of many uses, easily taking off epiphragma can be well bonding with multiple tank body material, is applicable to the fields such as beverage, pot foods, medical supplies, microwave food.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1 is a kind of structural representation easily taking off epiphragma of the present invention.
Detailed description of the invention
As shown in Figure 1 easily take off epiphragma, be composited by three floor height Molecularly Imprinted Polymers, bonding with sealing 1 is internal layer 21, and all the other are two-layer is middle level 22 and outer 23.
Make the polybutene copolymer of internal layer 21 or ethene improved-acrylic materials, have good fissility, resistance tocrocking and thermal viscosity, can prevent from easily taking off epiphragma 2 and pollute article in container, can make again easily to take off epiphragma 2 can peel off from sealing 1 easily; Excellent thermal viscosity makes easily to take off epiphragma 2 good heat seal strength and wider heat-sealing window, thus improves the package speed of packing producing line, reduces chip rate, improves production efficiency; Conventional tank body material has polypropylene, polystyrene, polyvinyl chloride and polyester resin etc., can according to tank body material, and the internal layer 21 easily taking off epiphragma 2 selects polybutene copolymer or ethene improved-acrylic resin.
Described middle level 22 is the mixture of low density polyethylene and metallocene low density polyethylene (LDPE), can improve compound fastness, increases the caking property with internal layer 21, makes easily to take off epiphragma 2 and there will not be layering and wire drawing phenomenon.
Described outer 23 is the mixture of low density polyethylene and metallocene low density polyethylene (LDPE), can increase the combined strength bination between outer 23 and the lid 3 being adhered to outer 23, prevents lid 3 and easily takes off epiphragma 2 and occur lamination.
General, easily take off the skin 23 of epiphragma 2, middle level 22 and internal layer 21 Thickness Ratio by the pro rate of 3:4:3.Certainly, under technical staff instructs, the thickness proportion of outer 23, middle level 22 and internal layer 21 is adjustable.The thermal viscosity of easily taking off epiphragma 2 is increased, then the thickness of corresponding increase internal layer 21 as needed.
Easily take off the using method of epiphragma, it comprises the steps:
Extrusion process is used to be bonded with the lid 3 of container by the described skin 23 easily taking off epiphragma 2;
According to the size of sealing 1, lid 3 described in cutting;
By heat-seal technique, in the sealing 1 internal layer 21 of described lid 3 being adhered to container and airtight container.
When described easily take off epiphragma 2 be positioned at the sealing 1 of same plane for encapsulating profile time, the sealing effectiveness easily taking off epiphragma 2 is best.
Above embodiment is only not limited in order to technical scheme of the present invention to be described, all do not depart from spirit and scope of the invention any amendment or equivalently to replace, it all should be encompassed in the scope of technical solution of the present invention.
