Hot melt adhesive is the abbreviation of hot melt adhesive, is an important category of adhesive industry, with 100% solid content, solvent-free, environmental protection and non-toxic, fast curing characteristics, widely used in automated packaging, hygiene products, label tape, automobiles, construction, furniture and furniture, printing and binding, shoes, clothing and other industries. Usually refers to the solid at room temperature, when heated to a certain temperature, it melts into a viscous liquid, after coating, wetting the sticky, after pressing, cooling to room temperature, the bonding is completed within a few seconds. In order to give full play to the advantages of hot melt adhesive in bonding, it is necessary to match the corresponding quality and reliable hot melt adhesive with high-quality hot melt adhesive.
Hot melt adhesive products have been applied to all aspects of people's lives, covering people's eating, wearing, living, using, traveling, playing in various fields, eating bowls of instant noodles, drinking bottles of water, drinking a glass of wine, wearing clothes, shoes, hats, buildings, houses, cars, trains, planes, refrigerators, color TVs, washing machines, toilet paper, toothpaste, soap, handicrafts to beautify living space, decorative paintings, craft flowers, children's toys, gifts, etc., all have the application of hot melt adhesive. It can be said that in modern people's lives, the application of hot melt adhesive is everywhere. Today, I will mainly talk about the application of hot melt adhesive in the packaging industry.
Packaging hot melt adhesive refers to the hot melt adhesive applied to automated packaging, bonded to the side and seal of the carton, hot melt adhesive has fast curing, strong initial adhesion, low melting viscosity, easy flow, and has certain low temperature resistance and high temperature resistance. Carton packaging hot melt adhesive, carton sealing form, sealing hot melt adhesive has partially replaced the tradition of strapping packaging and packaging tape.
In fact, the application of hot melt adhesives in the packaging industry has always been the best existence in hot melt adhesive applications. Development to the present, the common hot melt adhesive sealing process application in the packaging industry, in addition to the common manual hot melt glue gun glue sealing boxing, has gradually emerged high-speed hot melt adhesive automatic sealing machine and hot melt adhesive particles, hot melt adhesive blocks; The advantage is that the glue speed, the amount of glue can be precisely controlled, the speed is faster and more efficient; Suitable for large and small cartons, small cartons high-speed sealing, improve production efficiency.
Advantages of using packaged hot melt adhesives:
1. Good packaging quality: The transportation carton must be able to withstand temperature, humidity changes and brutal loading and unloading, and it is difficult for general tape and glue to meet this requirement. Hot melt adhesive and wet matter has a good bond, strong penetration, in the corrugated paper and liner board at the same time play a physical and chemical bonding role, the bonded carton overall strength is enhanced, carton is not easy to deform and crack.
2. High low temperature resistance: general glue or tape, in the northern cold climate, it is easy to open the glue; The hot melt adhesive has good low temperature resistance and can be used in the environment of -30~-40 °C. Moreover, the storage period of hot melt adhesive is up to 2 years, the storage area is small, and there are no special storage requirements.
3. Beautiful appearance: Merchants require that while transporting goods, the packaging can also convey the product and company image through the packaging pattern design. At this time, the advantages of hot melt adhesive come into play, it is bonded between the folding wings, which can provide a larger display space.
4. Low cost: the use of hot melt adhesive sealing is fast, the whole bonding process only needs 1~3 seconds to complete, suitable for mass production, less energy consumption, low cost.
5. Strong anti-theft performance: hot melt adhesive also provides a good anti-theft function, because the adhesive penetrates into the corrugated, any attempt to open the carton will tear the fibers.
