Each solution has its own unique features, which are worth analyzing, taking into account the requirements of a specific project. The key question is: packaging tape - Which adhesive to choose? The answer depends on the surface, conditions of use and specific needs.

2. how does the adhesive in packaging tapes work?

2.1 Adhesion mechanism

How an adhesive bonds to a surface - adhesion and cohesion

The basic action of the adhesive is based on two processes: adhesion and cohesion.

Adhesion is the ability of a substance to adhere to the surface to which it is applied. For packaging products, the compatibility of the adhesive with different materials, such as paper, plastic, metal or cardboard, is crucial.
Cohesion refers to the adhesive's internal cohesive strength, which ensures its durability after application. The better the cohesion, the lower the risk of delamination during use.

The two processes work together to make the product effective. For example, hot-melt solutions are distinguished by strong initial adhesion, while the packaging tapes with solvent adhesive has higher cohesion, making it reliable in harsher conditions.

Factors affecting the performance of the adhesive:

• Surface type: Smooth materials, such as glass or metal, require adhesives with greater adhesion, while rough cardboard works better with more flexible adhesives.
• Application temperature: Low temperatures can reduce the adhesive's ability to bond, so solvent adhesive products are better in cold conditions.
• Humidity and contamination: Dirt or moisture on the surface can weaken the strength of the bond, which should be taken into account when choosing.

2.2 Differences between adhesives

Effect of chemical composition on adhesion and durability

Each type of adhesive used in packaging materials has a different chemical composition that affects its properties:

• Acrylic: Created on the basis of aqueous emulsions. Resistant to UV radiation and aging, but less effective at low temperatures.
• Hot-melt: Made of synthetic rubber. Provides high initial adhesion, but is less durable under high temperature fluctuations.
• Solvent: Contains natural rubber. It handles moisture, extreme temperatures and difficult surfaces perfectly.

These differences mean that the answer to the question "which adhesive to choose?" depends on the specifics of the application.

How to choose the right adhesive for packaging tape?

3.1 Surface types

Cartons
Hot-melt solutions are most often chosen for standard-textured packaging, as their high adhesion allows quick and effective sealing. For rougher surfaces, solvent adhesive products that adhere better to irregular structures will be better.

Foils and slippery surfaces
For wrapped items such as food products, acrylic solutions are recommended for their versatility and resistance to peeling in wet conditions. However, for slippery films, hot-melt may prove more effective.

Rough surfaces
For materials such as wood or textiles, solvent adhesives work best, as their flexibility ensures a durable and secure bond.

3.2 Storage and transportation conditions

Effect of temperature
The choice of a suitable solution should take into account temperature conditions:

• Low temperatures: Products with solvent glue maintain adhesion even in sub-zero temperatures, making them indispensable for cold storage and winter transportation.
• High temperatures: Acrylic adhesives are more resistant to heat and UV radiation, making them ideal for outdoor applications.

Humidity and light exposure
Long-term storage in damp warehouses requires solvent adhesives that do not lose their properties when exposed to moisture. Acrylic solutions, while UV resistant, may not do well in high humidity environments.

3.3 Purpose

Short-term use
For one-off tasks, such as quickly sealing a package for shipment, hot-melt adhesive products that offer instant bonding and are economical will be suitable.

Long-term storage
In situations where packaging will be stored for long periods of time, especially in harsh environments, solvent adhesives are the best choice due to their durability and resistance to aging.

Choosing the right adhesive is a key element in ensuring the effectiveness and durability of packaging. With the right fit, you will avoid problems with peeling or lack of adhesion in harsh conditions
