Which industry customers have odor requirements for hot melt adhesives?

Published on Dec. 25, 2019

The smell of hot-melt adhesive comes from the hot-melt adhesive itself, which is an essential characteristic of hot-melt adhesive, and is affected by raw materials, production processes and circulation links. Hot-melt collagen material is composed of main resin, tackifiers, thinner or softening oil, and additives. The inherent odor of raw materials is an important source of hot-melt odor. For example, most EVA hot melt adhesives have a slight acetic acid smell. Rubber also has its own taste, but it has different shades. The rosin-based tackifying resins in the tackifying resin have the taste of turpentine, while the C9C5 resins have their different tastes. Even all hydrogenated resins have their own taste, but Our sense of smell may not be able to detect it, and other raw materials are also more odorous, just different in intensity and intensity. In the production process, the hot melt adhesive may also have a new odor source, and the purpose of reducing odor can be achieved through the control of the production process. In the hot melt adhesive logistics transportation, it may also be stained with new odors.

1.EPE packaging industry

The shock-proof and drop-resistant packaging material EPE assembly for electrical packaging requires end users to have no odor in the glue. In the production and assembly process of EPE packaging manufacturers, the glue applicator is open, the local heating temperature is high, and the production workers It is particularly allergic to odors, and it is considered that odors are toxic, which affects health and requires a safe working environment. Therefore, hot melt adhesives are required to have extremely strict odor requirements, and hot melt adhesives are required to have no odor.

2. Hygiene products industry

In recent years, the sanitary products industry, such as baby diapers, sanitary napkins, and adult care pads, has set extremely high requirements for the odor of hot melt adhesives, and requires that hot melt adhesives be odorless. With the development of the economy and society, people are getting richer and richer, and have higher requirements for product quality. In addition, with the fact that there is only one child in China, everyone wants their children to enjoy the best treatment, even for infants. Diapers, I also hope that children can use the safest and most comfortable, which is absolutely unacceptable for products with odor. In order to meet the requirements of end customers, it is reasonable for sanitary products manufacturers to require raw materials manufacturers of sanitary products to be tasteless.

3. Food packaging industry

In recent years, food safety has received more and more attention. There are indeed too many unsafe foods in our lives, such as poisoned milk powder, poisoned rice, trench oil, dead pork, fake medicine, fake wine, expired moon cakes, expired milk, etc. Wait, even some well-known domestic big brands that promote "small wins by wisdom, big wins by virtue" are selling poisoned milk powder. Chinese users really don’t know who to trust and who to trust, the overall image of Chinese brands Was severely hit. Odors, especially odors, are considered unsafe, so manufacturers of food, beverage, beer, and other requirements for hot melt adhesives have no odor requirements, and odorless bonding makes users feel safe, assured, and practical.

4. Automotive interior industry

The automobile is China's second largest industry and the largest industry. With an annual output and sales of more than 22 million vehicles in 2014, China is transforming from a big automobile country to a strong automobile country. In the automotive indoor environment, people are increasingly unable to tolerate the irritating indoor environment. Automobile brand manufacturers have established automotive interior environmental standards and require VOCs to meet standards. The VOC is derived from automotive interior materials, so it is required that the VOC of the hot melt glue for automobile interior bonding is up to standard, and there is no volatile substance and no odor. However, there are many unacceptable odors in VOC-compliant cars, and the relationship between VOCs and odors has become a research proposition.
