TW419419B - Method of producing packing bag with gas-permeable effect - Google Patents

Abstract

This invention relates a method of producing packing bag with gas-permeable effects, comprising passing two plastic tapes, arranged up and down oppositely, through a set of front hot-sealing knife so as to sew the tapes to form two rows of rectangular hot-sealing points spaced at intervals; using a set of rear hot-sealing knife to carrying out a hot-sealing and cutting in between the two rows of rectangular hot-sealing points to form a hot-sealing line; moving the two plastic tapes a distance and using the front hot-sealing and back hot-sealing knives to sequentially sewing to form two rows of rectangular hot-sealing points and hot-sealing and cutting the two rows to continuously produce packing bags. The packing bag made according to the above mentioned method are sewed with a row of rectangular hot-sealing points on the both sides of the bag, and the inner side of the rectangular hot-sealing point is formed with an gas-permeable hole so that a row of rectangular hot-sealing points can reinforce the hot-sealing line so as to avoid the rupture of the hot-sealing line of the packaging bag. Furthermore, the gas-permeable hole of the rectangular hot-sealing points can discharge the air inside the packing bag to reduce the volume of the bag after packing and avoid the rupture of the packing bag under pressure.

Description

ί 419419 It is clearly stated that the effect of airbags made by the French side of the production of airbags has a variety of purposes. Especially, the airtight side and the inner side are linearly sealed. The two-point bag inside the hot side is sealed with a heat pack. It ’s time to do this, and the method is to make a sealed bag for heating and heating. A rectangular package can be reduced and reduced, and the bag inside the package can be avoided by avoiding the break of the gas line. The hole is formed by a hot-seal through the gas line, and the heat is strongly formed. The hole is bagged. The broken product is broken and the material is under pressure. It can be protected by its bag or the package. The avoidance package can be used and the sealed hot bag with the “general integration” of the back-loading as the bottom should go in #J 和Two, the mouthband bag is a plastic shape, the hem is folded, and the fold is slightly different. It is tied, glued, and lined. A bag with a hot bag should be packed into the product by borrowing it. . Or a bag, a bag

D includes the time of study. Packing the clothes into the bag will be able to use the mouth bag to open the bag at the 'seal' when the bag is glued, and then seal the eager and thin and thin seals. The bag with two straight knifes on the side can be refilled with one bag, and the bag can be packed with two on the side only. The bag is lined and sealed, and the bag a # is broken. Make the bag, pack into a tightly packed surface of the bag, make it with plastic, and add a tie to pull the tie. The high-seal line seals the hot side of the bag. The damaged side of the bag is broken. The two bags are packed in the bag. The bag holder should be easily refilled, so that the larger and more integrated bag can make tr air easier. If the rate is lower than the drop rate, the shipment will be lower than the drop bag, and it will be loaded, waited for 10,000 packs, and shipped and transported. Such as the 'lost and thrown items will be broken and often easy to pass.' If the packing speed is fast and convenient, it is necessary to make it for the bag. It is very irritable. After the easy-to-dispose material is accumulated on the empty surface, the bag is packed in a bag and the bag is broken. The ground is dropped and the bag is filled.

P.4 4194 1 9 states that the sealing material was damaged due to another quality factor. I dirty hot foot made of various materials side original type two glue strong plastic bags some line seals are equipped with heat sealing package for heat. Now, the damage is caused only by time and law, and the side-sealed type of heat-sealing bag with a small square knife is packed in a bag that ca n’t be sealed and packed into a bag. It will be packed and shrinked to make it. The production line will be certain. When the seal is known, it is used to heat-seal the package and heat up. When the package is empty in this way, the glue is hot-formed. It will be easy to move the main two groups after it is plasticized. Just tear it out of your hands, cut each quilt in one break, the easy method is to cut the side line with the air volume, and then two seals are empty and made because of the knife. Heat-sealed, easy-to-fabricate, hot-swappable bags before loading and unloading are easy to pack into this package, and then shipped. One of the moments when the package is low, the package has a low cracking effect, the package is sealed, and the efficiency is reduced. The bag is arranged first. The bag is packed first. The product has a shape of a pair of moments with a shape and a body. The pair of pairs of open and closed bags, which are laid out with seams, are installed, and the two lines get off the ground. When the seal is broken and the two upper knives are broken, the tape will be sealed and cut to seal and heat, and the thermal distance of the hot section of the sealing method, which is the distance from the sealing point to the sealing point, will be a square-shaped moment. Describing the plastic car with rubber seams on the two sides of the belt.-The car has two bags each, which can be installed on the inner side and then on the side of the bag to seal the two subsequent hot-made bag lines. The front part, one of them, the bag has a small breaking moment and reduces the 'product body'.

Seal •, the shape of the package L is made of two consecutive consecutive heats, and one of them is shaped by the shape of the heat, and the second is the same as above. According to the above, 1 bag of 11 ki is used to break Sr. 2 The shape of the 1 reed line is sealed and torn by the 1 line borrow bag to be filled with heat. When it is wrapped to avoid avoidance, it is opened with α 'bag. 2. Open a line and lower the heat to reduce the heat. —Η, broken. The bag of sexuality is packed by the packing competition system 2 and the low market knife is lowered and the high seal is heated. It is packed with the cracks that were previously cracked and quilted. © Packing first squeezes the lower and lowered bags.

4194 1 9 V. Description of the invention (5) There is a gap s between the outer side and the inner side of the block 2 1 1. As shown in the fifth figure, the upper sealing knife 2 1 is pressed against the two plastic bands 1 a, After 1 b, two rows of rectangular heat seal points 1 1 are formed, and the outer side of the rectangular convex block 2 1 1 of the upper sealing knife 2 1 is slightly higher than the inner side, so that the produced _outer slope _ ^^ becomes a breathable The holes 1 1 a are shown in the sixth and seventh figures. And because the " packing kl's bag mouth must be sealed by the adhesive surface 1 3 on it, and after the packaging bag 1 is sealed, the rectangular heat-sealing point 1 1 _ vent hole 1 1 a Exclude the air in the packaging bag 1 to reduce the volume of the island after packaging, and then, when it is transported by throwing it, it will rupture if it is impacted when it is dropped on the ground, or the packaging bag 1 ruptures under pressure, Therefore, it is necessary to prevent the packaging bag 1 from being broken due to dropping the ground, causing the packaged material to be scattered on the ground, and the loss caused by contamination of the packaged material. To sum up, the manufacturing method disclosed in the present invention has not existed in the past, and it can indeed achieve the above-mentioned effect. It already has the elements of an invention patent, and has applied for an invention patent in accordance with the law. I hope that the Bureau will review and grant the patent. To pray.
