                        How to use bottle hot melt adhesive label?

Labeling hot melt adhesive is mostly used for plastic bottle labels, such as Coca-Cola, Wahaha and other plastic bottles of outsourcing paper bonding, bonding material is polyethylene plastic bottles (PET, PE, PP, etc.) and PP, PE plastic film; Most of the construction process is strip construction, need to achieve good temperature resistance, smooth construction requirements, special customers will also pay attention to color requirements, generally choose colorless transparent as the best.

The so-called good temperature resistance requirements refer to:
First, these bottles are often transported through containers, and the temperature can reach 60-70 degrees Celsius during transportation, and the binding agent must not flow in this environment, without losing viscosity, and without overflow.
Second, most bottles will have a refrigeration process, at this time the label glue needs to be not brittle, not degumming; Therefore, the hot melt adhesive for bottle and package sticker must meet the requirements of high and low temperatures at the same time.

In terms of construction, the label glue making process is a relatively fine process, with fast time, less gram weight and small cross-section.
Hot melt adhesive in the construction to achieve smooth need to achieve several points:
First, the melt viscosity of the glue is low, that is, a thinner glue.
Second, no wire drawing, in the rapid construction of the assembly line once the glue drawing will affect the beauty and die and the service life of the equipment, the cost of cleaning will also increase.
