The types of hot melt adhesive include: ethylene vinyl acetate (EVA) adhesive
Ethylene vinyl acetate (EVA) is a polymer based material used for standard packaging of industrial hot melt adhesives. EVA produces high-performance and highly competitive packaging hot melt additives. Ethylene vinyl acetate is considered the primary choice for many applications as it offers one of the largest performance ranges among all currently available applications. Ethylene vinyl acetate can function in both traditional and low-temperature hot melt adhesives.
Polyethylene is a polymer substrate suitable for pallet sealing and cardboard box applications. These adhesives have an extremely low odor, light color, and are easy to peel off from metal surfaces, making them easy to clean. Polyethylene is not suitable for bonding substrates, therefore it is suitable for use at traditional application temperatures.
Metallocene polymers have existed for decades. They combine with other components to provide great stability forhot melt adhesiveproducts. They provide storage temperature intensity in both hot and cold conditions. They have become the fastest-growing polymer base. Metallocene minimizes the decomposition caused by thermal exposure and reduces carbonization, while expanding the cold and hot bonding properties. Some of the products available today contain metallocenes in their adhesives; However, many variants with different stability, price points, and bond performance are different from the original product.
Amorphous poly (alpha olefin) (APAO) is mainly used in areas with long working hours or where it needs to be bonded to plastics. These types of adhesives have a sticky, soft, and very flexible texture. This makes them a very good choice for assembling products, including adding foam for corrugated packaging protection and bonding corrugated plastic containers.
Polyamide adhesives are excellent in places where high temperature resistance is required. They are also useful in situations where rapid assembly strength, solvent and oil resistance are required. Polyamide is considered an excellent choice for wood, filters, and other applications that require high performance. Polyamide requires extreme temperature applications of approximately 400 ° F (204 ° C). However, like other types of adhesives, they do not exhibit significant stability when heated.
Determine whether the material used to make the box is the same as before, and whether the surface has been treated, such as copperplate paper, with completely different properties from the original one. The performance differences of hot melt adhesives for the same purpose in the market are not significant. It will be difficult to […]
Direct answer: When printing and packaging companies conduct environmental impact assessments or apply for pollutant discharge permits, it involveshot melt adhesiveThere are usually five types of particle information – product MSDS (Safety Data Sheet), component and solid content description, VOCs and non methane total hydrocarbons generation basis, annual dosage and process addition method description, supplier […]
The performance and effect of the hot melt adhesive used for producing hand-held paper bags of different materials vary depending on the model used. Choose the right one< strong> Suitable for hand-held paper bags used for expensive gift packaging. Generally, white cardboard is used as a material for making hand-held paper bags. For white cardboard […]
More and more manufacturers are using EVA hot melt adhesive to process books and other materials, regardless of the size of the processing plant, there will still be an upward trend in the future. This is because using this adhesive has the advantages of fast book publishing, short cycle time, beautiful appearance of books, and […]
