There are many types of adhesives in packaging industry. Hence, it is important to know which type of adhesive is used and works best to seal the packaging material effectively. Knowing the types of adhesives will help you to choose the right adhesive for packaging.

The different types of adhesives can be distinguished by how they form the bond between two objects, based on their chemical composition, classification, and physical form.

The adhesives in packaging industry used include Hot Melt Adhesives, Pressure- Sensitive Adhesives, Solvent-Based Adhesives, Starch-Based Adhesives, and Water-Based Adhesives. Each of them come with their own unique benefits and characteristics; and are made for different applications and conditions.

Starch Adhesive formulation involves two processes In a saucepan

• Add cornstarch, light corn syrup, and vinegar over medium heat whisk water, until they are well-blended.
• Stir the mixture constantly until the mixture thickens.

In an airtight container in which you want to store starch adhesives,
• Whisk ¼ cup of cornstarch and ¼ cup of water together until they become smooth.
Finally, take the saucepan off heat.

Starch Adhesive Uses

In the packaging industry, starch adhesive uses are commonly found in corrugated boxes, paper products, and paper bags (like grocery bags). Aside from these, other common starch adhesive uses include envelopes, labeling, laminating, wallpaper paste, and tube winding (like paper-towel roll).

What makes starch adhesives so good for these uses are they are thicker than other adhesives; possess better fluid properties and quicker tack; can be applied at either hot or cold temperatures; and above all, is extremely economical.

Starch adhesive uses can also be widely found in corrugated board applications. They are preferred because corrugated board applications favor vegetable glue die to its strong bond, quick tack, and economical cost.

Starch-Based Adhesive for Corrugated Boxes

Corrugated boxes are the most popular method of delivering consumer goods.

Hence, choosing an adhesive to secure corrugated boxes is a critical decision. That’s because, the boxes need to remain sturdy throughout shipping and handling. Besides, the adhesive you choose can also significantly impact recycling and how the boxes break down in the trash zone.

When it comes to the best adhesive, starch-based adhesives remain the best choice.

What makes the starch-based adhesive for corrugated boxes a preferred choice is it

• Dries and gelatinizes, creating in the bargain a strong bond between the cardboard pieces without in any way saturating the material. As such, it can be relied upon to assemble sturdy shipping boxes that are ready for transit.
• Offers robust stability and strength. It bonds cardboard materials so well that it will ensure the products remain safe and secure during travel journey. Additionally, it can maintain and sustain its bond in a wide array of environments and temperatures. This makes it a reliable choice for shipping boxes.
• Has a minimal environmental impact, since its ingredients come from renewable resources like corn and rice. A starch adhesive does not contain toxic chemicals making it less harmful to the environment when it decomposes. Besides, using a natural adhesive helps to reduce packaging waste, conserve resources, and promote an eco-friendly and healthy environment.
• Is inexpensive as it is a renewable resource that is readily available in abundance; and the natural materials can be obtained to produce the adhesive. This can effectively reduce production and shopping costs leading to lower overall prices.

Finally, by using starch-based adhesive for corrugated boxes, companies can establish and market their brand and products as eco-friendly and sustainable.
