Hot Glue for Cardboard Boxes

Hot melt adhesives provide flexibility in terms of being applied to various materials. This post specifically looks at the assembly of corrugated plastics and cardboard packaging. This method of packaging is commonly utilized by various sectors, such as food and beverage suppliers, e-commerce packaging, and relocation companies. Continue reading to discover information about these common packaging materials, as well as the usual hot melts and applicators used in making them.

Corrugated Packaging: What Is It?

Three main varieties of corrugated plastic are available in different shapes and sizes. Laminated sheets, profile sheets, and honeycomb, which are also known as bubble sheets, are included. Moreover, it is probable that people have come across corrugated cardboard. It is composed of a fluted corrugated sheet and one or two flat linerboards. Both are utilized for creating various types of packaging, specifically boxes and carrying cases.

Benefits of Corrugated Packaging

• Long-lasting

• Lightweight

• Cheap to produce and put together

• Able to be used again

• Multifunctionality of use

• Does not take in moisture (plastic packaging)

• Able to be recycled

Hot Melts Adhesives and Applicators Ideal for Corrugated Package Assembly

Hot Melts

Hot melt adhesives are frequently utilized in constructing corrugated packaging because of their quick setting time, strong bonding capabilities, and flexibility. Specific types of hot melt adhesives and applicators are most suitable for corrugated package assembly. Below are some suggestions for hot melt adhesives and applicators that are appropriate for assembling corrugated packaging.

1. Ethylene Vinyl Acetate (EVA) Hot Melt Adhesives:

EVA hot melt adhesives are frequently utilized in the assembly of corrugated packages because of their strong adhesion to different materials, flexibility, and relatively low melting temperature. They create a robust connection between layers of corrugated cardboard, guaranteeing the strength and longevity of the packaging.

2. Polyurethane PUR Hot Melt

Polyurethane hot melt, also known as PUR hot melt, is an adhesive heated and applied from a cartridge or slug using a heated gun or bulk dispensing equipment. PUR is distinctive in that it hardens by reacting with moisture in the atmosphere, creating a durable connection that cannot be reversed by heat.

Applicators

Manufacturers should take into account their production area, staff's familiarity with hot melt handling, and budget constraints when choosing suitable equipment. Listed below are a few hot melt applicators that are ideal for the assembly of corrugated plastic or cardboard packaging.

Benchtop “Hands-Free” Units

This feature guarantees high-quality packages with a flawless hot melt bead on every carton, rapid packaging with easy operation, cost savings on adhesive with a perfect glue bead, and secure gluing with hands-free operation.

Hot Melt Roll Coaters

Roll coaters enable quicker production rates, precise application, consistent outcomes, and enhanced product quality. Constructed for longevity, these units are created to outperform expectations in challenging work environments.

Industrial Hot Glue Guns

Industrial hot glue guns combine functionality, durability, and user-friendliness in an ideal way. With these characteristics, applying hot melt to corrugated surfaces becomes very easy.

PUR Hot Melt Machinery

PUR hot melt equipment provides stronger bonding than many other types of adhesives, such as water-based adhesives and different hot melt adhesive formulations. This kind of hot glue and dispenser is perfect for joining corrugated plastic.
