Hot melt adhesive and oil adhesive which is more suitable for use in the food industry

In the food industry, hot melt adhesive and oil adhesive have their own characteristics and application scenarios, but in general, hot melt adhesive is more suitable for label pasting in the food industry because of its environmental protection, non-toxic, strong viscosity and adapt to a variety of materials. Here's a detailed comparison of the two:

Hot melt glue

advantage

Environmentally friendly and non-toxic: Hot melt adhesive is usually made of environmentally friendly materials, non-toxic and tasteless, and meets the safety requirements of the food industry.

Strong viscosity: the hot melt adhesive has good adhesion, which can ensure that the label is firmly pasted on the food packaging and is not easy to fall off.

Adapt to a variety of materials: hot melt adhesive can adapt to a variety of materials, including paper, plastic, metal, etc., to meet the diversified needs of food packaging.

Easy processing: Hot melt adhesive is coated on the paste after heating and melting during processing, and quickly solidifies after cooling, with high processing efficiency.

Application scenario

Food packaging label paste: such as milk, juice, drinks and other packaging labels.

Sealing of food boxes and cans: to ensure the tightness of food during transportation and storage.

Oil glue

advantage

Strong adhesion: Oil adhesives may exhibit stronger adhesion than hot melt adhesives in some cases.

Good waterproof performance: oil adhesive has good waterproof performance, suitable for label pasting in humid environment.

shortcoming

Poor environmental protection: Compared with hot melt adhesives, oil adhesives may be less environmentally friendly, and some oil adhesives may contain chemical components that are harmful to the human body.

Higher cost: The production cost of oil glue may be higher than that of hot melt glue, increasing the cost of food packaging.

Application scenario

Although oil adhesives are widely used in some industrial areas, they are relatively rarely used in the food industry due to environmental concerns.

Comprehensive comparison

Environmental protection: hot melt adhesive is better than oil adhesive, more in line with the safety requirements of the food industry.

Adhesive relay: Both have strong adhesive relay, but hot melt adhesive is enough to meet the demand in food packaging.

Cost: Hot melt adhesives usually cost less, which helps to reduce the overall cost of food packaging.

Processing convenience: hot melt adhesive processing is convenient, suitable for large-scale automated production.

conclusion

Therefore, in the food industry, hot melt adhesive is more suitable for food label paste because of its environmental protection, non-toxic, strong viscosity, suitable for a variety of materials and convenient processing. Of course, when choosing the specific type of glue, it is also necessary to comprehensively consider factors such as the specific needs of food packaging, the material to be affixed and the production process.
