Description

Seamless plastic woven heat-sealed packaging bag

technical field

The utility model relates to a packaging product, in particular to a seamless plastic-woven heat-seal packaging bag.

Background technique

Plastic woven bags are widely used in the packaging process of fertilizers, chemical products, daily necessities, food and other products. During the use of plastic woven bags, the upper and lower seals can be sewn with thread, but the sealing effect is not good, and the waterproof and moisture-proof performance is poor. Way.

At present, most of the sealing tapes in the market are equipped with a hot-melt adhesive layer to bond and seal the seal, and a hot-melt adhesive layer is set for bonding, which can meet certain adhesive packaging sealing requirements, but at low temperatures, the hot-melt adhesive layer tends to lose its viscosity , resulting in weak bonding, thereby reducing the sealing and waterproof and moisture-proof performance of plastic woven bags.

In addition, the anti-counterfeiting technology of product packaging has attracted much attention, and the anti-counterfeiting performance of plastic woven bags and sealing tape products needs to be improved.

Utility model content

The utility model provides a seamless plastic-woven heat-seal packaging bag with good low-temperature sealing performance, recyclable reuse, waterproof and anti-counterfeiting performance.

The utility model adopts the following technical solutions:

A seamless plastic-woven heat-seal packaging bag, comprising a bag body, the two ends of the bag body are respectively provided with seals, the seals are bonded with heat-sealing tapes, and the heat-sealing tapes include waterproof and moisture-proof plastic film layers arranged in sequence, The base layer and the polymer layer coated on the base layer. The polymer layer is bonded to the bag body. The heat-sealing tape has the advantages of low-temperature heat sealing and excellent weather resistance, and improves the sealing, waterproof and moisture-proof of the packaging bag. performance.

The material of the base layer is the same as that of the bag body, and the overall material of the recycled packaging bag is the same, which can be directly recycled and granulated for reprocessing and utilization without separating different materials, which is convenient for recycling and reuse after use.

According to customer requirements or actual needs, the outer surface of the heat-sealing tape is provided with an anti-counterfeiting pattern layer to improve the anti-counterfeiting performance of the heat-sealing tape, and also improve the anti-counterfeiting performance of the overall product during use.

Preferably, the waterproof and moisture-proof plastic film layer, the base layer and the polymer layer of the heat-sealing tape are heat-coated together in three layers.

The materials of the bag body and the base layer are preferably both PP or PE, and the high-molecular polymer layer of the heat-sealing tape has high bonding strength with PP and PE materials.

The bag body includes a plastic woven cloth layer and a coating layer, and the plastic woven cloth layer is made of PP or PE. In order to improve the anti-counterfeiting performance, the outer surface of the bag is also provided with an anti-counterfeiting pattern layer.

Advantage and beneficial effect of the present utility model are:

The utility model adopts heat-sealing adhesive tape to bond and seal without needing stitches, which improves the sealing strength of the packaging bag, and the overall strength of the packaging bag can reach the degree of fiber tearing;

The material of the packaging bag of the utility model is the same as that of the adhesive tape, and can be recycled and granulated at the same time, which is green and environmentally friendly;

The packaging bag of the utility model has excellent performances in all aspects, especially for powdery packaging materials, after being sealed, it has no leakage, is moisture-proof, and is anti-fission, and improves the anti-counterfeiting function of the product.
