The application of hot melt adhesive for hand-held bags

The use of hot melt adhesive for hand-held bags is becoming increasingly widespread. This type of bag has a high biodegradability and recyclability, which has led to an exponential increase in its popularity in various activity fields. Manufacturers have designed safety references for using hot melt adhesives for this purpose.

There is no doubt that paper bags are more popular than plastic bags, mainly because they are biodegradable and recyclable. In many industries – textiles, pharmaceuticals, catering, etc… But especially in the food industry, they are used to sell a wide range of products, many of which are bulk products.

There are countless kinds of paper bags on the market. They come in different weights, thicknesses, colors or handle types. Made of laminated paper, cardboard, fine paper or glossy paper, any one of them must meet its main design goal: to resist all types of loads, from the lightest to the heaviest. This guarantee is highly demanded by paper bag manufacturers and can only be achieved by using hot melt adhesive.

The application of hot melt adhesive for hand-held bags in paper bag manufacturing involves all stages of its production.

For example, in a single-layer bag, use hot melt adhesive to bond the side seams. Since these are quick glues, the bonding between the substrates will be completed in a very short time.

Bonding of the handle (smooth, curly rope, pressed…) It is also nourished by hot melt adhesives. In most cases, use paper strips that are folded and adhered to the finished bags. Due to the rapid bonding and ease of joining any type of surface of hot melt adhesive, hot melt adhesive is used at this stage.

The use of this type of hot melt adhesive in folding bottom bags has also become widespread. These can generate strong and rapid adhesion when applied and ensure airtight sealing.

In any case, it must be taken into account that hot melt adhesives have higher performance, and their application is very simple, which is conducive to reducing time and is also beneficial for high-speed production without generating glue threads.

The characteristics of hot melt adhesive for hand-held bags:

1. Quick bonding.

2. Good adhesion.

3. It has wide flexibility at low temperatures.

4. Excellent bonding for the most common types of paper.

5. Low odor.

6. The fiber breakage rate is high when attempting to peel.
