Abstract
The invention provides a seamless plastic-woven heat-sealing packing bag and a manufacturing method thereof, and belongs to the technical field of packing. The seamless plastic-woven heat-sealing packing bag comprises a base layer, and a high-molecular polymer layer which covers the base layer by coating. The seamless plastic-woven heat-sealing packing bag is characterized in that a heat-sealing tape is formed by coating the high-molecular polymer layer on the base layer under the temperature of 200 to 300 DEG C; the base material is manufactured from PP (Propene Polymer) or PE (Poly Ethylene); the high-molecular polymer layer is prepared through polypropylene, high-melting-index polypropylene, an ethylene-vinyl acetate copolymer and a cross-linking agent. According to the seamless plastic-woven heat-sealing packing bag, the heat-sealing tap is used for adhering and sealing an opening of a plastic-woven bag, so that sewing by a needle can be saved, and the sealing intensity of the packing bag can be improved, and the overall strength of the packing bag can reach the fiber tear strength.
Description
Technical field
The present invention relates to heat sealed package bag is compiled in a kind of seamless modeling, belong to packing technique field.
Background technology
Polywoven Bag is widely used in the packaging of the products such as fertilizer, chemical products, articles for daily use, food.Prior art
In, the upper lower sealing of Polywoven Bag generally uses cotton rope suture, and its sealing effectiveness is not good, and waterproof, humidity resistance are poor, and
Suture sealing part tensile load, skimming resistance be not good, easily breaks a seal, in transportation particularly in packet procedures are fallen.In addition,
Suture sealing woven bag in removal process, it is necessary to take out stitches, pick after can just carry out, waste time and energy, relatively costly.
For solving the defect for sealing, waterproof moisture-proof effect is not good, in prior art, also there is setting hot melt adhesive layer viscous to sealing
Connect the scheme of sealing.The program can meet certain bonding package encapsulation and require, which still suffers from the following two kinds weak point：Its
One, waterproof, moistureproof problem is solved, a ply of paper outside the body of prior art package, is compounded with, when woven bag is reclaimed, it is difficult to
Ply of paper is separated with plastics, is reclaimed difficult；Second, at low temperatures, hot melt adhesive layer easily loses viscosity, causes bonding not
Jail, so as to the sealing for reducing Polywoven Bag and waterproof and dampproof performance.
Content of the invention
The present invention is directed to problems of the prior art, and it is good to provide a kind of low temperature seal performance, recyclable recycling
Heat sealed package bag is compiled in seamless modeling.
The technical scheme that the present invention is specifically adopted is：
Heat sealed package bag is compiled in a kind of seamless modeling, and including bag, bag is respectively arranged at two ends with sealing, and the sealing part is bonded with
Heat sealing adhesive tape, the heat sealing adhesive tape includes basic unit and the high polymer layer being coated in basic unit, the high molecular polymerization
Nitride layer is bonding with bag, it is characterized in that, the heat sealing adhesive tape is that high polymer layer is coated on basic unit at 200～300 DEG C
Upper and obtain, wherein, the high polymer layer include by polypropylene, high melting means polypropylene, ethylene-vinyl acetate copolymer and
Cross-linking agent is made.
For strengthening the water resistance of woven bag of the present invention, it is additionally provided with bag outer surface and heat sealing adhesive tape base layer exterior surface
Waterproof and dampproof plastic membranous layer.
In the present invention, high polymer layer includes to be obtained by mixing, extrusion, pelletize by the raw material of following weight parts：
Wherein, the cross-linking agent is double (the tert-butyl peroxy base) -3 of 1,1-, 3,5- trimethyl-cyclohexanes (BPMC), double (tertiary fourths
Peroxy isopropyl base) benzene (BIPB), 1,2- divinylbenzene and three allyl chlorinated isocyanurates are according to 1:1:0.2:0.2 mixes.
In the present invention, the raw material for being adopted is commercial goods, for example：Random polypropylene can select the trade mark be APP4 or
The commercial goods of APP5, high melting means polypropylene can select the commercial goods of the trade mark for 1600d of Tai Su company production.
In the present invention, the basic unit is identical with the material of bag, and after recovery, packaging bag entirety material is identical, directly can reclaim
Pelletize, reprocessing is utilized, without the need for separating unlike material, the recycling after convenient use.
In the present invention, the preparation method of the heat sealing adhesive tape, comprise the steps：
1) mix：The various raw materials of high polymer layer are mixed in proportion
2) extrude
3) pelletize
4) it is cast
5) it is coated with：The coating is carried out at 200～300 DEG C；
5) heat seal：Waterproof and dampproof plastic membranous layer is heat sealing in basic unit；
6) cut, obtain heat sealing adhesive tape finished product.
Wherein, the material of the bag and basic unit is preferably all PP or PE material.
Beneficial effects of the present invention：
1st, the present invention is sealed using heat sealing adhesive tape bonding, is stitched without the need for pin, is improve the sealing intensity of packaging bag, and packaging bag is whole
Body intensity is up to fiber tearing degree.
For verifying the effect of the present invention, applicant entrusts sealing of product quality inspection academy in Shandong Province's to a length of 1 meter
The woven bag of adhesive tape and three present invention is checked according to GB/T 8946-2013, and survey report numbering is：PL052979-
2016, assay is as follows：
| Sequence number | Inspection project | Unit | Assay |
| 1 | Tensile load | N/50mm | 916 |
