Abstract
The present invention is the preparation method of a kind of overlay film Polywoven Bag, first melt extrude, by extruder, the thin film that is in a liquid state after pp material grain, master batch and Masterbatch uniformly being mixed, carry out the most rapidly cooling to be allowed to be solidified into solid primary film, cut into the nascent flat filament that width is, finished product flat filament is obtained after carrying out thermal finalization again, send into loom and be made into woven bag fabric, as the braiding base fabric of overlay film；Then at dual coating polypropylene and the mixture of polyethylene of braiding base fabric, sided corona treatment is carried out；Finally it is folded into stand-by packaging bag shape, and carries out carrying out pressing after heat treatment is allowed to melt to the overlay film of joint with hot blast.The present invention is coated with thin film in the surfaces externally and internally both sides of traditional woven bag, not only increases the intensity of woven bag, and is of value to the printing quality of the outer surface improving woven bag, also makes woven bag be not susceptible to leakage when containing powder material.
Description
Technical field
The present invention relates to packaging bag field, particularly relate to the preparation method of a kind of overlay film Polywoven Bag.
Background technology
The main production of Polywoven Bag is to utilize polypropylene or polyethylene flat filament, through being produced through knitting device
Product, the usage amount of Polywoven Bag is very big, is widely used in the packaging of the article such as fertilizer, chemical products.Owing to braiding uses
Crisscross transmission, makes woven bag be provided with and good draws resistance and anti-penetration performance, but cause surface owing to longitude and latitude interweaves
Uneven, not only have impact on the outward appearance that product is overall, be unfavorable for printing pattern clearly on surface, and as powder
Packaging bag time easily from longitude and latitude interweave gap leak.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and the preparation method of a kind of overlay film Polywoven Bag is provided.
The present invention for achieving the above object, by the following technical solutions: the preparation method of a kind of overlay film Polywoven Bag, its
Being characterised by, its step is as follows:
(1) melt extruded by extruder after pp material grain, master batch and Masterbatch uniformly being mixed be in a liquid state thin
Film, melt temperature is 175 DEG C, carries out the most rapidly cooling and is allowed to be solidified into solid primary film；
(2) primary film is drawn to knife rest by haulage drum, cut into the nascent flat filament that width is 8mm, then will be nascent
Flat filament obtains finished product flat filament after carrying out thermal finalization, heat setting temperature is 60 DEG C；
(3) finished product flat filament feeding loom is made into woven bag fabric, as the braiding base fabric of overlay film；
(4) in dual coating polypropylene and the weight ratio of the mixture of polyethylene, polypropylene and polyethylene of braiding base fabric
For 3:1；
(5) the braiding base fabric being coated with polypropylene and polyethylene film being carried out sided corona treatment, magnitude of voltage is set to 15kV；
(6) the braiding base fabric that the dual coating after sided corona treatment is crossed polypropylene and polyethylene film is folded into stand-by packaging
Bag shape, and carry out carrying out pressing after heat treatment is allowed to melt to the overlay film of joint with hot blast；
(7) bottom of the braiding base fabric after overlay film is sewed up, during stitching, use polyester thread.
Particularly, in described step (1), the mass fraction of pp material grain, master batch and Masterbatch is respectively polypropylene
Particulate material 90 parts, master batch 9.5 parts, Masterbatch 0.5 part.
The invention has the beneficial effects as follows: the present invention is coated with thin film in the surfaces externally and internally both sides of traditional woven bag, no
Improve only the intensity of woven bag, and be of value to the printing quality of the outer surface improving woven bag, also make woven bag contain
Leakage it is not susceptible to during powder material.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
The preparation method of a kind of overlay film Polywoven Bag, it is characterised in that its step is as follows:
(1) mass fraction being respectively 90 parts of PP GRANULES material, master batch 9.5 parts, the polypropylene that Masterbatch is 0.5 part is former
Material grain, master batch and Masterbatch melt extrude, by extruder, the thin film that is in a liquid state after uniformly mixing, and melt temperature is 175 DEG C, so
Carry out the most rapidly cooling to be allowed to be solidified into solid primary film；
(2) primary film is drawn to knife rest by haulage drum, cut into the nascent flat filament that width is 8mm, then will be nascent
Flat filament obtains finished product flat filament after carrying out thermal finalization, heat setting temperature is 60 DEG C；
(3) finished product flat filament feeding loom is made into woven bag fabric, as the braiding base fabric of overlay film；
(4) in dual coating polypropylene and the weight ratio of the mixture of polyethylene, polypropylene and polyethylene of braiding base fabric
For 3:1；
(5) the braiding base fabric being coated with polypropylene and polyethylene film being carried out sided corona treatment, magnitude of voltage is set to 15kV；
(6) the braiding base fabric that the dual coating after sided corona treatment is crossed polypropylene and polyethylene film is folded into stand-by packaging
Bag shape, and carry out carrying out pressing after heat treatment is allowed to melt to the overlay film of joint with hot blast；
(7) bottom of the braiding base fabric after overlay film is sewed up, during stitching, use polyester thread.
Above the present invention is exemplarily described, it is clear that the present invention implements and is not subject to the restrictions described above,
As long as have employed method design and the various improvement that carry out of technical scheme of the present invention, or the most improved directly apply to other
Close, all within protection scope of the present invention.
