Setting different heat sealing temperatures for different materials of Yangzhou garment bags

Currently, Yangzhou garment bags are widely used in industries such as shirts, knitwear, apparel, textiles, clothing accessories, lingerie, underpants, and children's wear. More and more clothing brand merchants are starting to value the role of garment bags for their products. A well-crafted garment bag not only brings convenience to consumers but also helps companies better promote their products and leave a deeper impression. Therefore for an enterprise, if the outer packaging of the product is neglected, even if the product is made very well, it will still affect its sales. In Yangzhou garment bag production process, heat sealing temperature is also a very important aspect that deserves attention. If the Yangzhou garment bag heat sealing temperature is insufficient, it is very likely to cause air leakage or cracking ...and other phenomena to occur, affecting the quality of Yangzhou garment bags. Therefore, to ensure the garment bag's heat sealing temperature, different temperatures need to be set for different materials. garment bag's So, what are the different materials' garment bag's different heat sealing temperature setting methods? ? Below, professional flexible packaging manufacturer Shunxingyuan Packaging will explain, based on years of experience from their workshop bag-cutting masters, that only by setting the heat sealing temperature correctly can exquisite garment bags be produced.

 Different materials' different setting methods for heat sealing temperature:

1、 LDPE ：

This is a very commonly used heat-sealing resin, which can be produced into film by extrusion blowing or extrusion casting and then used in composite films with other films. It can also be extrusion coated or laminated on other films, aluminum foil, or paper, or co-extruded with other resins to form composite films. Its melting point is at 105℃~120℃ and its heat sealability, transparency, and non-toxicity are good.

2、 MDPE and HDPE ：

melting points are at 120℃~135℃ , also have good heat sealability, but their transparency is not as good as LDPE , their crystallinity is higher than LDPE , film strength is higher than LDPE , and heat sealing temperature is higher than LDPE . Generally speaking, PE 's optimal heat sealing temperature is at 150℃~160℃ , at which point it has the highest heat sealing strength.

3、 PE Copolymers of:

PE with other α -carbon atom olefins, such as octene, pentene, etc., and metallocene (MPE) 、 LLDPE etc., as well as copolymers of ethylene with acrylates, ethylene with vinyl acetate, ethylene with maleic anhydride, etc. The common features of these resins are good low-temperature heat sealability, high heat sealing strength, and good hot tack.

The content introduced above describes the different materials' Yangzhou garment bag different setting methods for heat sealing temperature. Heat sealing temperature is Yangzhou garment bag an important indicator among them; its quality directly relates to whether the product can be well protected , affects the quality of Yangzhou garment bags, and also impacts product sales.
