Description

Seamless plastic woven heat-sealing packaging bag
Technical Field
The invention relates to a seamless plastic woven heat-seal packaging bag, and belongs to the technical field of packaging.
Background
The plastic woven bag is widely applied to the packaging of products such as fertilizers, chemical products, daily necessities, foods and the like. In the prior art, the upper and lower seals of a plastic woven bag are generally sewn by using thread ropes, the sealing effect is poor, the waterproof and moisture-proof performances are poor, the tensile load and the peeling resistance at the sewing seal are poor, and the plastic woven bag is easy to unseal in the transportation process, particularly in the bag falling process. In addition, the woven bags with the seals sewn need to be taken out of the stitches and picked in the recycling process, so that time and labor are wasted, and the cost is high.
For solving the not good defect of sealed, dampproofing and waterproofing effect, also have among the prior art to set up the hot melt adhesive layer and bond sealed scheme to sealing. The scheme can meet certain bonding package sealing requirements, and still has the following two defects: firstly, the problems of water resistance and moisture resistance are solved, a paper layer is compounded outside the body of the packaging bag in the prior art, and when the woven bag is recycled, the paper layer is difficult to separate from the plastic, so that the recycling is difficult; secondly, under the low temperature condition, the hot melt adhesive layer loses viscidity easily, causes and bonds insecurely to the sealed and dampproofing and waterproofing performance of plastic woven sack has been reduced.
Disclosure of Invention
Aiming at the problems in the prior art, the invention provides the seamless plastic woven heat-seal packaging bag which has good low-temperature sealing performance and can be recycled.
The invention specifically adopts the technical scheme that:
the seamless plastic woven heat-seal packaging bag is characterized in that the heat-seal adhesive tape is obtained by coating a high polymer layer on a base layer at the temperature of 200-300 ℃, wherein the high polymer layer comprises polypropylene, high-melt index polypropylene, ethylene-vinyl acetate copolymer and a cross-linking agent.
In order to enhance the waterproof performance of the woven bag, waterproof and moistureproof plastic film layers are arranged on the outer surface of the bag body and the outer surface of the heat-seal adhesive tape base layer.
In the invention, the high polymer layer is prepared by mixing, extruding and granulating the following raw materials in parts by weight:
Figure BDA0001113040690000021
wherein the cross-linking agent is formed by mixing 1, 1-bis (tert-butylperoxy) -3, 3, 5-trimethylcyclohexane (BPMC), bis (tert-butylperoxyisopropyl) benzene (BIPB), 1, 2-divinylbenzene and triallyl isocyanurate according to the ratio of 1:1:0.2: 0.2.
In the present invention, the raw materials used are all commercially available products, for example: the random polypropylene is commercially available under the trade designation APP4 or APP5, and the high melt index polypropylene is commercially available under the trade designation 1600d from Taiwan plastics corporation.
In the invention, the base layer and the bag body are made of the same material, and the whole packaging bag is made of the same material after recovery, so that the packaging bag can be directly recovered, granulated, reprocessed and utilized, and is convenient to recover and recycle after use without separating different materials.
In the invention, the preparation method of the heat-sealing adhesive tape comprises the following steps:
1) mixing: mixing the raw materials of the polymer layer in proportion
2) Extrusion
3) Granulating
4) Tape casting
5) Coating: the coating is carried out at 200-300 ℃;
6) And (3) heat sealing: heat-sealing the waterproof and moistureproof plastic film layer on the base layer;
7) And (5) cutting to obtain a finished product of the heat-seal adhesive tape.
Wherein, the preferred material of bag body and basic unit is PP or PE material.
The invention has the beneficial effects that:
1. the invention adopts the heat-sealing adhesive tape for bonding and sealing without needle sewing, thereby improving the sealing strength of the packaging bag, and the integral strength of the packaging bag can reach the fiber tearing degree.
In order to verify the effect of the invention, the applicant entrusts Shandong province product quality inspection research institute to inspect the sealing adhesive tape with the length of 1 meter and three woven bags of the invention according to GB/T8946-: PL052979-2016, test results as follows:
serial number Inspection item Unit of Test results
1 Tensile load N/50mm 916
2 Peeling force N/30mm 16.8
2. The invention is green and environment-friendly, and is specifically represented as follows: 1) the wire is not required to be removed, and the wire can be directly recovered, so that the time and the labor are saved, and the cost is low; 2) all the materials selected by the invention can be recycled; 3) the invention does not use organic solvent, thus avoiding environmental pollution.
3. The high molecular polymer layer of the invention has strong adhesive force and low heat sealing temperature (about 80-100 ℃).
