Description
Technical Field
The invention relates to the technical field of packaging bags, in particular to a PBT (polybutylene terephthalate) environment-friendly packaging bag and a production process thereof.
Background
At present, online shopping is increasingly becoming the shopping habit of most people, for self-operated e-commerce enterprises, the logistics packaging operation also faces great working intensity, and meanwhile, the packaging used as a material also becomes an important expenditure cost of the e-commerce enterprises; the packing mode of wide application in aspects such as the transportation of electronic product transportation, fragile article, valuables and food is that the packing carton is placed to the wrapping bag inside, protects article through the dual cooperation of packing carton and wrapping bag, and the wrapping bag is made by the PBT material: however, the method has the defects that on one hand, the cost of the packaging bag and the packaging box is high, the packaging bag is not recycled, on the other hand, when the size of the article is large and heavy, the worker cannot easily take and place the article when moving the packaging bag, and the article is damaged due to shaking in the taking and placing processes; if people twine the handle through the sticky tape, too extravagant and effect are not good.
If a chinese patent with application number cn201520256462.x discloses an anti-collision packing bag, the technical proposal is composed of an outer bag and an inner bag, the length of the outer bag is equal to that of the inner bag, the width and thickness of the outer bag are larger than those of the inner bag, and the two inner bags and the outer bag are sealed by adopting a middle three-side sealing mode; the inner bag is positioned in the middle of the inner part of the outer bag, the outer bag is overlapped with the upper sealing edge and the lower sealing edge of the inner bag and is a composite sealing edge, the sealing edge of the inner bag is longer than the composite sealing edge of the outer bag, and the lengthened sealing edge is positioned in the outer bag; the articles are stored in the inner bag, the two bag bodies are inflated, and the inflation saturation of the outer bag is greater than that of the inner bag; the anti-collision packaging bag is manufactured on the premise of increasing the use of packaging materials as little as possible. The anti-collision bag is a product with a good anti-collision effect, provides an outer package with a good effect for products with high anti-collision requirements, and has a relatively low price; however, the technical scheme has certain disadvantages, the technical scheme cannot be moved conveniently, vibration is generated in the moving and placing processes, and the objects are affected, so that the objects are damaged; meanwhile, the sealing operation after the articles are placed into the packaging bag needs machine operation, and the packaging bag cannot be suitable for fragile articles with different specifications, so that the limitation of the technical scheme is caused.
In view of this, in order to overcome the technical problems, the invention provides a PBT environment-friendly packaging bag and a production process thereof, and the technical problems are solved.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention provides the PBT environmental-friendly packaging bag and the production process thereof, the binding belt is arranged on the surface of the bag body, and the second groove is uniformly arranged on the other surface corresponding to the bag body to be matched, so that the purpose that the binding belt can be clamped with the second groove is achieved, the packaging bag can be firmly sealed by the binding belt, articles can be firmly wrapped by the bag body, the packaging weight is reduced, and the bag body is moved by the binding belt, so that the articles are prevented from being damaged in the process of convenient transportation.
The PBT environment-friendly packaging bag comprises a bag body, wherein a first groove is formed in one surface of the outer surface of the bag body; a binding belt is arranged in the first groove; the part of the binding belt close to the bottom end of the bag body is in sliding connection with the first groove, and the end face of the binding belt close to the bag body is fixedly connected with a fixing hook; the other side corresponding to the outer surface of the bag body is uniformly provided with a second groove; the second groove is arranged corresponding to the first groove, and the number of the second groove is at least two;
when the packaging bag and the packaging box work, the cost of the packaging bag and the packaging box is high, and the packaging bag is not recycled; when the size of the article is large and heavy, the worker cannot easily take and place the article when moving the packaging bag, and the article is damaged due to shaking in the taking and placing processes; if the handle is wound by the adhesive tape, the waste is excessive and the effect is poor;
the bag body is folded, the internal volume of the bag body is compressed, so that the object is fixed in the bag body, the binding belt is moved immediately, bypasses the surface of the bag body, and is fixed on the corresponding second groove through the fixing hook, so that the binding belt can firmly seal the bag body, the moving space in the bag body is reduced, the object is bound, the shaking of the object in the bag body is reduced, and the object is prevented from being damaged in the process of moving the bag body; the worker can conveniently and quickly move the bag body through the binding belt, so that the bag body is convenient to move and place;
according to the invention, the binding belt is arranged on the surface of the bag body, and the second groove is uniformly arranged on the other surface corresponding to the bag body to be matched, so that the purpose that the binding belt can be clamped with the second groove is achieved, the bag body can be firmly sealed by the binding belt, the bag body can firmly wrap articles, the packaging weight is reduced, and the bag body is moved by a worker through the binding belt, so that the articles are prevented from being damaged in the process of convenient transportation.
Preferably, the inner surfaces of the bag bodies are provided with a third groove; the section of the third groove is rectangular;
when the bag works, the third groove is uniformly formed in the inner surface of the bag body, and an operator can plug the air bag into the third groove, so that the air bag can not move in the bag body, articles in the bag body are further fixed, the moving space in the bag body is reduced, the articles are bound, the shaking of the articles in the bag body is reduced, and the articles are prevented from being damaged in the bag body moving process; so that the object is wrapped and fixed by the air bags in the bag body;
according to the environment-friendly PBT packaging bag, the third groove is uniformly formed in the inner surface of the bag body, and the third groove is matched with the air bag filled in the third groove, so that the air bag in the bag body cannot shake according to the stress of the bag body, articles in the bag body are further protected from being damaged due to impact, and the protection performance of the environment-friendly PBT packaging bag on the articles is improved.
