Packaging Adhesives


Packaging adhesives play a vital role in the packaging industry. Without these specialized glues and bonding materials, it would be nearly impossible to manufacture packaging efficiently and meet all regulatory standards. From food and beverage packaging to consumer goods and electronics, adhesives are what allow today's complex packaging designs and constructions.

Hot Melts

Hot melts, also known as thermoplastic adhesives, are perhaps the most widely used type of packaging adhesive. Comprising around 30-35% of the global adhesive market, hot melts have become the adhesive of choice for package construction due to their ability to be applied at high speeds on automated packaging lines. Hot melts are thermoplastic polymers that remain solid at room temperature but become liquid and adhesive when heated.

Some of the main applications for hot melts in packaging include case and carton sealing, tray forming, lamination, and stiffening of carton flaps and corners. The versatility of hot melts allows packaging manufacturers to quickly and reliably bond everything from corrugated boxes to flexible pouches to rigid plastic containers on high-output production lines.


New water-based and hot melt formulations being developed each year are driving increased sustainability in packaging. Researchers are working to reduce VOCs and incorporate recycled materials into hot melt resins to create adhesives with lower environmental impact. Bio-based resins from renewable resources like sugar cane are another area of innovation. These greener hot melts allow the packaging industry to decrease its carbon footprint over time.

Solvent-Based Adhesives

While hot melts dominate for applications requiring high speed bonding, solvent-based adhesives continue filling critical needs as well. Comprising synthetic and natural resin systems dissolved in organic solvents, solvent adhesives are able to form extremely strong, durable bonds across a wide range of surfaces.

Key applications of solvent Packaging Adhesives include laminating foil and film layers in food packaging, die-cut lid and flexible packaging bonding, carton sealing, and case making. Solvent adhesives offer excellent plasticizer and moisture resistance well-suited for harsh production environments and lengthy product shelf lives. However, solvent emissions present environmental and workplace safety concerns that have driven development of new lower-VOC and solvent-free formulations.

Water-Based Adhesives

As environmental and safety regulations have tightened globally, water-based adhesives have gained significant traction as a "greener" alternative. Comprising emulsions of acrylic, polyvinyl acetate (PVA), and other polymers dispersed in water, water-based adhesives are free of VOCs and HAPs (hazardous air pollutants).

Some leading applications of water-based packaging adhesives include case and carton sealing, corrugated lamination, and flexible laminations. Their versatility makes them well-suited to bonding corrugated containers, folding cartons, self-adhesive labels, and various paper and film-based packaging substrates. Many water-based formulas can match or exceed the bond strength of solvent competitors as well.

Recent advancements in water-based adhesive technology focus on improving heat resistance for retort and hot-fill applications, decreasing drying times through advanced formulations, and tailoring properties for bonding innovative new packaging materials like compostable films and coated paperboards. As regulations continue to drive the industry toward more eco-friendly options, the market potential for water-based adhesives in packaging looks very promising.

Natural Adhesives

While comprising a relatively small portion of the overall packaging adhesive market currently, natural adhesive systems derived from plant and animal sources are gaining attention due to their renewable nature. Natural adhesives in packaging applications include those based on casein, starch, soy, and various gum and resin extracts.

Key end uses involve case sealing, tray forming operations, lamination bonding, and corrugated box making. Although bond strength and efficiency may sometimes lag synthetic resins, natural adhesives offer compelling sustainability benefits. Ongoing formulations research is working to enhance performance properties while leveraging the "natural" marketing angle to appeal to environmentally-conscious consumers.


From hot melts dominating high-speed case and carton sealing lines to water-based innovations enabling safer lamination and package assembly, adhesives will continue providing critical functionality throughout the complex packaging industry. Factors like evolving regulations, raw material sourcing strategies, and consumer demand for sustainability will drive ongoing research and new product development globally. With constant technological advancements, adhesives are sure to remain the glue cementing packaging constructions for many years to come.

Food Release Agents Play an Important Role in Ensuring That Food Remains Intact and Does Not Crumble

Image
Food Release Agents Food Release Agents are substances that are used to prevent food from sticking to cooking surfaces during the cooking process. These agents can be in the form of sprays, powders, or liquids and are commonly used in baking, frying, and grilling. In this article, we will explore the different types of Food Release Agen, their uses, and their benefits. There are several types of Food Release Agen, each with its unique properties and uses. The most commonly used Food Release Agen are: Vegetable Oil: Vegetable oil is a popular food release agent used in baking, frying, and grilling. It is easy to apply, inexpensive, and readily available. Vegetable oil can also enhance the flavor of the food being cooked. However, vegetable oil can sometimes leave a greasy residue and can burn at high temperatures. Cooking Spray: Cooking spray is a convenient and easy-to-use food release agent. It is sprayed directly onto the cooking surface and provides an even coating. Cooking spray is...

Amines: Essential Molecules In Biological Systems

Image
Amines What are Amines? Amines are organic compounds that contain basic nitrogen atoms with a lone pair of electrons. They are derivatives of ammonia (NH3) wherein one or more of the hydrogen atoms are replaced by organic substituents such as alkyl or aryl groups. Due to the presence of the nitrogen atom, amines have basic properties and can act as Brønsted bases. Classification of Amines Amines can be classified into three main categories based on the number of carbon atoms attached to the nitrogen atom: Primary Amines Primary Amines contain one alkyl or aryl substituent attached to the nitrogen atom. For example, methylamine (CH3-NH2), and ethylamine (C2H5-NH2). They are the most reactive category of amines. Secondary Amines Secondary amines have two carbon substituents attached to the nitrogen. Examples include dimethylamine ((CH3)2-NH) and diethylamine ((C2H5)2-NH). They are less reactive than primary amines but more reactive than tertiary amines. Tertiary Amines ...

Vaccine Adjuvants Improve Protection Against Infectious Diseases

Image
Vaccine Adjuvants Vaccine adjuvants are substances added to vaccines to enhance the body's immune response to a particular antigen, thereby improving the efficacy of the vaccine. Adjuvants have been used in vaccines for over 90 years, and they play a crucial role in the development of vaccines that are effective in preventing infectious diseases. The primary purpose of adjuvants is to stimulate the immune system's response to an antigen. Antigens are the substances in vaccines that trigger the immune system to produce antibodies. However, antigens alone are often not enough to produce an adequate immune response. Adjuvants work by enhancing the immune system's response to the antigen, making the vaccine more effective. Adjuvants are typically made up of various substances, including aluminum salts, oil emulsions, liposomes, and saponins. Each adjuvant has its unique characteristics, and the selection of adjuvants for a particular vaccine is based on several factors, includi...
