Abstract
The invention provides a plastic film blending material. Tensile strength and heat sealing strength of the plastic film blending material are increased greatly; the plastic film blending material is suitable for blow molding film preparation; heat-resistance temperature of the plastic film blending material is high; the plastic film blending material comprises polypropylene, polyethylene, and linear low density polyethylene. The invention also provides a processing method of the plastic film blending material.
Description
Technical field
The present invention relates to the technical field that packaging film is produced, be specially a kind of plastics film intermingling material and complete processing thereof.
Background technology
The current production and sales amount annual at China's plastics is about 6,000 ten thousand tons, wherein film article accounts for 30%, be widely used in family, food and drink, supermarket etc., there are wide market outlook, substantially adopt high density polyethylene(HDPE) and linear low density polyethylene to produce at present both at home and abroad and add plastics film, due to polyethylene structure, make that the intensity of its film product is low, heat sealability is poor.And polyacrylic intensity is high, heat sealability good, but material is softer is not suitable for blowing masking, and be widely used in production casting films, biaxial stretching film, and the heat resistance of existing film article is lower, heat resisting temperature is less than 100 degree, or uses under mark normal temperature.
Summary of the invention
For the problems referred to above, the invention provides a kind of plastics film intermingling material, improve tensile strength and the heat seal strength of film product significantly, blowing masking can be applicable to, its heat resisting temperature is higher simultaneously, invention also provides a kind of complete processing of plastics film intermingling material.
Its technical scheme is such: a kind of plastics film intermingling material, is characterized in that: it comprises polypropylene, polyethylene, linear low density polyethylene.
It is further characterized in that: described polypropylene is polypropylene PP, and described polyethylene is polyethylene HDPE, and described linear low density polyethylene is linear low density polyethylene LLDPE;
Described polypropylene is the polypropylene of Basel; Described polypropylene content is 5-10%, and polymerized ethylene content is 75-85%, and linear low density polyethylene content is 10-15%.
A complete processing for plastics film intermingling material, it comprises the following steps:
(1) polypropylene, polyethylene and linear low density polyethylene, is utilized to carry out blended;
(2) polypropylene, polyethylene and linear low density polyethylene after, blended are extruded by forcing machine;
(3) material, extruded through step (2) passes through mould molding;
(4), get device and draw by drawing and get the shaping material of step (3);
(5), by take-up mechanism batch shaping after material, form film finished product.
It is further characterized in that: draw the material after getting through step (4) and carry out embossing, trimming, rim charge winding successively.
In above-mentioned materials of the present invention, adopt the plastics film intermingling material of the blended production of polypropylene, polyethylene and linear low density polyethylene, substantially increase the tensile strength of product, heat seal strength, be applicable to blowing masking preferably, improve the heat resisting temperature of plastics film intermingling material simultaneously.
Accompanying drawing explanation
Fig. 1 is the complete processing schematic diagram of plastics film intermingling material of the present invention.
Embodiment
A kind of plastics film intermingling material, it comprises polypropylene, and its content is 5-10%, polyethylene, and its content is 75-85%, linear low density polyethylene, and its content is 10-15%.
Polypropylene is polypropylene PP, and polyethylene is polyethylene HDPE, and linear low density polyethylene is linear low density polyethylene LLDPE.
Polypropylene is the polypropylene of Basel.
Come by reference to the accompanying drawings to be further described the complete processing of plastics film intermingling material of the present invention:
See Fig. 1, a kind of complete processing of plastics film intermingling material, it comprises the following steps:
(1), utilize polypropylene, polyethylene and linear low density polyethylene blended: wherein polypropylene content is 5-10%, polymerized ethylene content is 75-85%, and linear low density polyethylene content is 10-15%;
(2) polypropylene, polyethylene and linear low density polyethylene after, blended are extruded by forcing machine;
(3) material, extruded through step (2) passes through mould molding;
(4), get device and draw by drawing and get the shaping material of step (3);
(5), draw the material after getting and carry out embossing, trimming, rim charge winding successively;
(6), by take-up mechanism batch shaping after material, form film finished product.
The present invention adopts polypropylene, polyethylene and linear low density polyethylene to mix the plastics film intermingling material produced, the processing of plastics film is due to the difference of material molecule structure and moulding process, and show larger difference, concerning a food flexible packing, select suitable material particularly important, the high performance polypropylene in Basel and polyethylene and linear low density polyethylene intermingling material is particularly adopted to produce freshness protection package, substantially increase the tensile strength of product, heat seal strengths etc., improve the heat resisting temperature of plastics film intermingling material simultaneously.
The transparent coiled strip sheet material of polypropylene, high density polyethylene(HDPE) and linear low density polyethylene blended production embossing, due to polyacrylic characteristic, the intensity of product, toughness, transparency, thermal viscosity, heat-sealing temperature etc. is made obviously to be better than polyethylene, so the physicals of blended embossed film, heat sealability is higher than sealed polyethylene plastic goods.
Technical study, trial-production is carried out for the principle of " research and development of polypropylene, polyethylene and linear low density polyethylene blended production embossing transparent coiled strip sheet material technique and material " and formula, technique etc.And physicals etc. has been carried out detection, compared:
The company that the complete processing of plastics film intermingling material of the present invention is produced contracts for fixed output quotas the detected result of the tensile strength of the transparent coiled strip of product and food preserving bag, heat seal strength and heat resisting temperature apparently higher than polyethylene product, meet the service requirements of user, and define complete technology, operational path.
Intermingling material of the present invention may be used for connecting simultaneously contracts for fixed output quotas the transparent coiled strip of product, and the company of improve contracts for fixed output quotas the integrally stretching intensity of the transparent coiled strip of product, heat seal strength and heat resisting temperature.
The present invention transforms original high-density film blowing device, autonomous design, processing, embossing device, cutting device, rim charge material collecting device are installed, make existing equipment can produce flat film bag, flat diaphragm material, also production embossing bag, embossed sheet can really accomplish a tractor serves several purposes.
