Hot melt Adhesives and Corrugated Paper Cartons

Hot-melt adhesives offer several advantages over other adhesive technologies. A few benefits include excellent adhesion, a quick set, and ease of use. Also, volatile organic compounds are reduced or eliminated, and the drying or curing step is eliminated compared to other adhesives. Hot-melt adhesives have a long shelf life and can usually be disposed of without special precautions.

What are hot melt adhesives?

Hot-melt adhesives (HMAs) are thermoplastic adhesives used in various bonding applications. Hot-melt adhesives are solid at room temperature and melt on heating at high temperatures. This is when they get their tacky property required to bond two surfaces. On cooling, they again solidify to create a permanent bond.

Hot melt adhesives

Hot melt adhesives are versatile adhesive products used in many industries. They offer superior strength and versatility to traditional glues and sealants, creating bonds that are often stronger than the materials they hold together. Powder adhesives, solvent adhesives, and speciality hot melt are important elements of the adhesive industry. These adhesives are used in various industries and applications by large-scale manufacturers and small businesses. Each type of adhesive has unique properties, making them ideal for certain tasks.

Packaging box manufacturers offer industrial packaging solutions to businesses in various industries. From custom designed corrugated boxes to plastic films and bags, the industrial package system helps keep products safe during transport and increases efficiency within the supply chain.

Glue bonding

Glue bonding is a process used to create strong, lasting bonds between two separate surfaces. Glue application involves various glues and adhesives to achieve this bond. A glue bottle is an essential tool for applying glue accurately and efficiently, while glue drops are small droplets of adhesive that can be used in combination with larger glues for added strength. Glue guns, glue machines and glue tape are essential for various projects. For example, whether you’re crafting with fabric or paper, using a glue gun to adhere to decorations is often the best way to secure a bond.

Box packing adhesive

Box packing adhesive is important for many box manufacturing and packaging companies. It is used to securely fasten boxes together so that products can be safely transported from one place to another. Box making machines are also essential for creating sturdy and quality boxes. The type of box packaging used will depend on several factors, including the size and weight of the product, how much protection it needs, and its intended use.

Corrugated boxes

Corrugated box manufacturers in Mumbai are responsible for meeting the demands of businesses for all kinds of cardboard box factory. These manufacturers have been supplying quality and durable cardboard boxes to companies for years, ensuring that their products can reach their destinations safely.

Manual glue dispenser

Manual glue dispensers are a great tool for those who need to dispense precise amounts of glue quickly and easily. Hot melt adhesive manufacturers in India now offer their products to global customers. They have developed a range of hot melt adhesive powders, hot melt base polymers and hot melt equipment that can be used for various applications.

Hot glue is available in a wide range of polymer technologies and has applications in manufacturing and end-use products. Hot-melt Adhesives do not require high drying time, unlike water-based or solvent-based adhesives. They offer the critical advantage of fast processing in production. Hot melt begins bonding almost immediately after application as it cools down and solidifies. This fast solidification is ideal for use on highly automated manufacturing lines that require rapid bonding.

Hot-melt adhesives have been used for various applications for decades. However, they have made their mark in the packaging industry to a great extent in recent years. Hot-melt adhesives are a small but essential component of modern packaging. One of the use cases of Hot-melt adhesives is in the corrugated paper board industry. Corrugated cartons, also known as master cartons or shipper cartons, are used for the packaging and transporting of every possible item worldwide. They are a very simple but essential component in packaging since they protect the things inside during shipping and handling.

Hot-melt adhesives in the manufacturing of master cartons

Corrugated boxes are a simple design requiring no complex manufacturing process. It involves cutting a flat sheet of groove and then folding and bonding its edges to create the final box.

Over the years, the most common methods used for the side flap pasting of master cartons include either the use of
(i) staples
(ii) water or solvent-based adhesives.

Staples vs Hot melt adhesives

1. Using Hot melt adhesives takes as much time as stapling the side flaps but costs much lower.
2. The material cost reduces by over 60% when using hot glue compared to staples.
3. Also, the stapling process cannot be fully automated for the high-speed production of master cartons.
4. Staples are made of iron; they rust very quickly, which is not acceptable for shipping a wide variety of goods. Stapled boxes are also not allowed for the packaging of items for exports. Non-rusting staple pins cost way more, usually made of SS or brass. Stapling is also not a recycling-compatible process.

Solvent based adhesives vs Hot melt adhesives

1. The most common method for side-flap gluing is using cold adhesives. These water- or solvent-based adhesives are liquid at room temperature, tacky, and do not require any preparations before use.
2. However, such adhesives take a very long time to dry and hence add a lot of delay and cost in manufacturing cartons.
3. Also, these adhesives have a high content of volatile organic compounds, which are not environmentally friendly.
4. With their quick drying properties, Hot-melt adhesives provide a massive advantage in time-saving at a similar cost

Hot melt adhesives in case of sealing applications

Product packaging

Product packaging and cardboard boxes for packing are ideal solutions for packing glue gun sticks and hot melt formulas. With these boxes, you can protect your products from damage during shipping and handling.

Packaging adhesives

Packaging adhesives is essential when bonding 3 ply boxes and 7 ply boxes. The adhesive bonding used in these boxes must be strong enough to hold the box together and flexible enough to allow for easy opening and closing.

Packaging blogs

Adhesive formulations, adhesive glue and adhesive materials are the foundation of successful packaging blog operations. Whether you’re an established business or just getting started, it’s essential to understand the different properties of adhesive options to get the most out of your product.

The packaging industry is constantly evolving. New trends, from traditional hot melts adhesive specialties to paper packaging for food, are emerging that require specialized machinery.

Box packing machine

The box packing machine adhesive uses have become increasingly popular in the industrial and packaging sectors. Hot melt tank technology has made it possible to produce stronger, faster bonds with greater accuracy.

Once the cartons are filled and their flaps folded shut, the cases need to be sealed to avoid spillage of contents and for easier handling.

Once the cartons are filled and their flaps folded shut, the cases need to be sealed to avoid spillage of contents and for easier handling. The most common method used for case sealing is BOPP tapes. Tapes are made of 70% plastic/paper backing, and only 30% of the adhesive is required for holding the carton flaps. However, tapes can easily be tampered with during transportation leading to pilferage and product loss. In addition, cartons sealed with hot glue tear on the opening, leaving clear signs of tampering.

Carton flaps are bonded with each other using hot glue and have much higher strength and sturdiness than tapes. This allows for taller and more giant stacks of cartons for transportation. It also allows using corrugated boards with lesser plies for manufacturing the same cartons, reducing costs.

Hot melt adhesives in the manufacturing of other items made of corrugated box

As the world tries to innovate with increasingly sustainable products and reduce our dependence on plastic, corrugated boards are finding uses in new ways. Due to their strength, lightweight, and long life, corrugated paper is used to manufacture POS/POP displays, furniture, etc. Hot-melt adhesives are the go-to choice for the bonding of corrugation in such products due to their various advantages over other adhesives.
