What Types of Adhesives Are Used for Corrugated Packaging?

Corrugated packaging adhesives are essential for corrugated boxes and other packaging materials made from corrugated boards. These adhesives or Craft Glues are used to join the various layers of the corrugated board together, forming a strong and durable packaging material that can protect the contents during shipping and handling.

The most commonly used adhesives for corrugated packaging are water-based adhesives, also known as starch adhesives. These adhesives are made from natural ingredients such as potato or corn starch and are non-toxic, making them safe for food packaging. They are also easy to clean and environmentally friendly, making them a popular choice in the industry.

In addition to water-based adhesives, other types of adhesives can be used for corrugated packaging, including hot melt adhesives, solvent-based adhesives, and pressure-sensitive adhesives. The choice of adhesive depends on factors such as the weight of the packaged contents, the environmental conditions during shipping and storage, and the type of packaging equipment used.

Various types of adhesives can be used for corrugated packaging, including:

1. Water-based adhesives: These are commonly used in corrugated packaging and are environmentally friendly. They are also easy to clean and do not emit harmful fumes.
2. Hot-melt adhesives: These adhesives are applied in a molten state and then cool to form a bond. They are fast-drying and provide a strong bond. However, they can emit harmful fumes and are not as environmentally friendly as water-based adhesives.
3. Solvent-based adhesives: These adhesives use solvents such as toluene or acetone to dissolve the adhesive and form a bond. They provide a strong bond but can emit harmful fumes and have environmental concerns.
4. Pressure-sensitive adhesives: These adhesives have a sticky surface that adheres to the corrugated surface when pressure is applied. They are commonly used in tape form and are easy to use.

The selection of adhesive type from an Adhesives Supplier will depend on the specific requirements of the packaging application, including the intended use, the weight of the packaged contents, the environment, and the transportation conditions.

The adhesive used for corrugated packaging must be carefully selected to ensure a strong and durable bond that can withstand the stresses and strains of transportation and handling. The quality of the adhesive is essential to ensure that the packaging remains intact and that the contents are protected during shipping and storage.
