Abstract
The invention discloses a thin film which comprises an outer layer, a middle layer and an inner layer with the composition ratios being 23%, 52% and 25% respectively. The invention further provides a production method of the thin film. The method comprises steps as follows: step one, mixing; step two, batching; step three, film blowing. The thin film provided by the invention has the characteristics of high surface layer friction force, small lining layer friction force and extremely high strength, and in combination of batching equipment, continuous production can be realized by a film blowing machine.
Description
Technical field
The present invention relates to film applications, particularly a kind of film and processing technology.
Background technology
Film is a kind of thin and soft transparent sheet.Make with plastics, adhesive, rubber or other materials, but more existing films are all use raw material to produce, the raw material that waste is a large amount of like this, production cost is high, particularly heat-sealing film.
Blown film (BlowMembrane) is a kind of plastic working method, refers to a kind of plastic processing plastic pellet heating and melting being blown out again film.If the film blown out with virgin material, uniform color, totally, finished product stretches.If with the plastic pellet made of waste plastics reclaimed, usually will add pigment when making film, the film made may be just painted irregular, crisp and easily broken, and price is also lower.The blown film material produced by the inflation film manufacturing machine of specialty is applicable to various high-grade blister-pack.This film is due to its good barrier property, fresh-keeping, damp proof, frost protection, oxygen barrier, oil resistant, can be widely used in weight packaging.As various fresh fruit, meat product, pickles, fresh milk, liquid beverage, medical supplies etc.If non-professional inflation film manufacturing machine or inflation film manufacturing machine do not make on sound lines in process, the coating materials so made also may be substandard products.Most of PE is used for blown film film processed, and standard low density PE (LDPE) or linear low close PE (LLDPE) all can be used.HDPE film-grade is generally used for the place requiring superior draftability and fabulous barrier properties.Such as, HDPE film is usually used in commodity bag, groceries bag and food Package.PE processing film is generally by common blown film processing or flat crowded processing method.
Because the scope of film application is different, the characteristic required has very large difference, be applied in some packaging, need the frictional force on top layer higher, and the frictional force of nexine is less, and requirement of strength is higher, also there is no a kind of easy volume production, friction subsurface power is high, nexine frictional force is little, intensity is high film at present.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of film and processing technology, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of film, comprise the skin at top, described outer downside is provided with middle level, internal layer is provided with on the downside of described middle level, the outer corona layer for being made up of corona layer PP Pipe Compound, described middle level is the polypropylene interlayer having polypropylene leftover pieces to make, and described internal layer is the hot sealing layer be made up of heat sealability plastics.
A processing technology for film, comprises the following steps:
1) batch mixing, to stir each raw material to scale by the percentage by weight of skin, middle level, each component of internal layer and makes former mixed materials for later use;
2) prepare burden, former mixed material step 1) prepared by the percentage by weight of skin, middle level, internal layer is prepared burden;
3) blown film, adopts the inflation film manufacturing machine blow molding of being furnished with Automatic batching equipment to produce the film of needs.
Preferably, described film heating, to 45 DEG C, then cools naturally.
The beneficial effect of above technical scheme is adopted to be: film provided by the invention has the advantages that friction subsurface power is high, nexine frictional force is little, intensity is high, and in conjunction with dispensing equipment, can realize continuous seepage by inflation film manufacturing machine.
Detailed description of the invention
The following detailed description of the preferred embodiment of the present invention.
The specific embodiment of the present invention: a kind of film, comprise the skin at top, described outer downside is provided with middle level, internal layer is provided with on the downside of described middle level, the outer corona layer for being made up of corona layer PP Pipe Compound, described middle level is the polypropylene interlayer having polypropylene leftover pieces to make, and described internal layer is the hot sealing layer be made up of heat sealability plastics.
A processing technology for film, comprises the following steps:
1) batch mixing, to stir each raw material to scale by the percentage by weight of skin, middle level, each component of internal layer and makes former mixed materials for later use;
2) prepare burden, former mixed material step 1) prepared by the percentage by weight of skin, middle level, internal layer is prepared burden;
3) blown film, adopts the inflation film manufacturing machine blow molding of being furnished with Automatic batching equipment to produce the film of needs.
Preferably, described film heating, to 45 DEG C, then cools naturally.
Film provided by the invention has the advantages that friction subsurface power is high, nexine frictional force is little, intensity is high, and in conjunction with dispensing equipment, can realize continuous seepage by inflation film manufacturing machine.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
