Abstract
The invention discloses an easy-torn film and a using method thereof. The easy-torn film for package is formed by compositing three-layer structures, wherein an inner layer is contact with a packed object, the rest two layers are a middle layer and an outer layer; the three-layer structures are made from high-molecular polymer materials, the inner layer is made from a mixture of low-density polyethylene and metallocene low-density polyethylene, the middle layer is a modified easy-torn polyethylene resin material, and the outer layer is a mixture of low-density polyethylene and linear low-density polyethylene; the easy-torn film packs an object by the steps of cutting, packaging and disinfecting. The easy-torn film and the using method thereof have the advantages that the process is simple, the film is easy to tear, and the use is convenient.
Description
Technical field
The present invention relates to a kind of film, particularly relating to a kind of easily tore film for packing being easy to tear.
Background technology
In order to protect article; film is often used to pack in articles for daily use; the easily tore film of current use be on film, inscribe line of cut with laser or with machinery by film serrate, effect film being reached easily tear, this method exists that working (machining) efficiency is low, technique defect rambunctious.
Summary of the invention
The present invention is intended to solve above-mentioned mentioned technical problem, provides that a kind of production efficiency is high, easy to use, the easily tore film easily torn and using method thereof.
The present invention is realized by following technical scheme:
A kind of easily tore film, being composited by three floor height Molecularly Imprinted Polymers, is internal layer, middle level and skin from inside to outside respectively; Described internal layer is the mixture of low density polyethylene (LDPE) and metallocene low density polyethylene (LDPE), and described middle level is that polyvinyl resin material is easily torn in modification, and described skin is the mixture of low density polyethylene (LDPE) and LLDPE.
Further, the Thickness Ratio of described skin, middle level and internal layer is 3:4:3.
A using method for easily tore film, it comprises the steps:
Described easily tore film is opened by design size cutting;
By edge sealing process, what the easily tore film after cutting is processed into openings at one side easily tears bag;
On a production line, use heat sealing machine to seal after bag easily being torn in article loading and easily tear bag;
Through intermediate links such as high-temperature sterilizations, complete and easily tear the packaging of bag to article.
Further, the heat-sealing temperature of bag is easily torn between 110-130 degree.
Beneficial effect is: a kind of easily tore film of the present invention have technique simple, be easy to tear and the advantage such as easy to use, be applicable to the fields such as facial mask, medicine and packaging for foodstuff.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:
Fig. 1 is the schematic cross-section of a kind of easily tore film of the present invention.
Detailed description of the invention
A kind of easily tore film, is composited by three floor height Molecularly Imprinted Polymers, is internal layer 11, middle level 12 and outer 13 from inside to outside respectively.
The low density polyethylene (LDPE) of described internal layer 12 and the mixture of metallocene low density polyethylene (LDPE), have good resistance tocrocking and thermal viscosity, can prevent easily tore film 1 from polluting packing material, easily tore film 1 can be made again to have good heat sealability, improve package speed, reduce chip rate, thus enhance productivity.
The easy-to-rupture that polyvinyl resin material can improve easily tore film 1 is easily torn in the modification in described middle level 12, and make easily tore film 1 transverse direction and vertically can tear easily, its breach also there will not be sawtooth.
The described low density polyethylene (LDPE) of outer 13 and the mixture of LLDPE, effectively can increase the combined strength bination between outer 13 and the material bonding with skin 13, make easily tore film 1 there will not be the phenomenon of layering.
General, the Thickness Ratio of the skin 13 of easily tore film 1, middle level 12 and internal layer 11 presses the pro rate of 3:4:3.Certainly, under technical staff instructs, the thickness proportion of outer 13, middle level 12 and internal layer 11 is adjustable.The thermal viscosity of easily tore film 1 is increased, then the thickness of corresponding increase internal layer 11 as needed; As the line easy-tear performance of easily tore film 1 need be increased, then the thickness in corresponding increase middle level 12.
A using method for easily tore film, it comprises the steps:
Described easily tore film 1 is opened by design size cutting;
Easily tore film 1 after cutting is processed into only have an opening easily tear bag;
On a production line, by article load easily tear bag afterwards and use heat sealing machine seal easily tear bag;
Through intermediate links such as high-temperature sterilizations, complete and easily tear the packaging of bag to article.
Further, the heat-sealing temperature packaging effect between 110-130 degree easily tearing bag is best.
Use the easily tore film 1 that above material is made, precut without the need to laser, simplify processing technology, improve operating efficiency; Easily tore film 1 is all easily torn at vertical and horizontal, and tear line linearly, and the edge of breach, without sawtooth and layering, uses simple and convenient.
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.
