Hot melt adhesives are ideal when simplified processing, streamlined manufacturing, and end-product protection are required. Hot melt adhesives are incredibly diverse and used in a wide range of packaging applications.
Consumer goods packaging continues to experience dramatic changes. From the need for sustainable packaging to food safety requirements and the rise in e-commerce, fast-moving brand owners are seeking ways to assure the safety and security of consumers, as well as the environment. Packaging for electronic devices, household appliances, toys, as well as food and beverage products and health and beauty items all have unique needs. Packaging is a critical element to keep products safe from damage and spoiling from outside forces.

- Carton sealing
- Tray forming
Consumer awareness continues to increase and impact buying behavior. Brand owners are driving change to meet increasing consumer demands like convenience, sustainability, and, most importantly, quality and safety. In between manufacturing of the product and arriving at retailers, the merchandise is prepared for shipping. Case and carton sealing is focused on sealing individual product packaging and consolidating the individual products into a shipping container. These adhesives are designed for clean machining, strong bonds, increased mileage, best possible efficiency, and compliance with the highest food safety and sustainability standards.
Cardboard trays are commonly used to transport fruit and vegetables from the field and then to distribution center or market. Tray forming adhesives facilitate the handling of products to the point of sales by providing a durable and food safe bond. Henkel’s portfolio of tray forming hot melt adhesives – TECHNOMELT® – addresses various performance requirements such as thermal stability and food safety requirements. Every consumer has specific needs that need to be met, such as protecting produce from crushing and contamination, prevent leakage and spillage, as well as meeting sustainability regulations for reuse and/or recyclability.
To meet growing consumer demand, efficient and safe transportation of containers and packages is crucial. Safe, sustainable, and efficient solutions are vital for the logistics of consumer goods companies. Specially designed adhesives can be integrated into the production process. Applying a hot melt adhesive in spiral or bead form on the top of the packaging enables the cases to be stacked and remain stable during stacking and transportation. Henkel’s TECHNOMELT® palletizing solutions offer an alternative to securing transport finished goods and reduce packaging waste and amount of plastic stretch film. Instead of wrapping pallets with stretch film to assure safe transport, Henkel’s range of hot melt adhesives effectively secure packages to the pallet, improving safety, and lowering overall costs.
The use of the right adhesives during labelling operations is a topic that affects production efficiency, sustainability, and consumer experience. Whether you are looking for adhesives for glass, plastic, or can labeling, our extensive selection of labeling adhesives offers excellent machinability and high adhesion and are designed to meet a range of requirements such as ice water resistance, hyper condensation, and PET recycling. Increasingly, innovative, and sustainable solutions are being developed such as, wash-off labeling adhesives that meet PET and glass recycling regulatory regulations. As an industry leader in adhesive solutions, Henkel has developed a range of sustainable solutions for both glass and plastic labeling.

Water-based adhesives are versatile, offering advanced bonding to meet demanding packaging applications.
In food packaging, adhesives are the silent but essential enabler to successful packaging solutions and are designed to meet safety standards in food packaging.
At Henkel, we are committed to setting new sustainability standards. As a leader in adhesive technologies, we understand how adhesives and coatings can impact packaging and provide innovative solutions to advance sustainable packaging.
Hot melt adhesives char can cause ongoing maintenance issues and product quality issues resulting in downtime on the production line. Once char infiltrates a system, it is difficult to completely flush out. Dead areas, such as bends and corners of tanks, will always exist and cannot be easily cleaned. Learn more on how to avoid char formation.
Routine maintenance and proper safety measures help to avoid preventable injuries. Contact with the hot melt liquid can result in serious burns. To keep operators safe, it is important to know the basic safety precautions when working with hot melt adhesives. Learn common best practices for hot melt safety.
Selection of the nozzle size on the applicator dictates the rate, flow, and amount of adhesive being dispensed onto a package. Nozzle size can also contribute to over application or under application of adhesive quantity. Learn how to optimize the nozzle size for your specific application needs.
During case and carton sealing, pop opens can occur for many reasons. Application settings, processing conditions, and ambient temperature can cause bond failure. Poor compression, higher line speeds, and the trend towards using recycled board stocks can increase the frequency of pop opens. To resolve and eventually prevent pop opens, it is essential to first understand the differences between various types of pop opens. Learn more on how to avoid pop opens.
When the hot melt adhesive is exposed to elevated temperatures for extended periods, hot melt adhesive can degrade and cause char. Implementing tank setback mode can avoid discoloration and char. It keeps the adhesive system running optimally. It’s the difference between downtime versus melt time. Learn more on how to implement setback mode.
When adhesive does not cleanly or completely separate from the extrusion nozzle, stringing can occur. These thin strands can cause issues with the seal and create machining issues. There are many ways to mitigate issues related to stringing and avoid production line issues. Learn more on how to eliminate stringing on the packaging line.
Across hot melt packaging applications, a key component is hot melt tank pressure, which impacts the rate of flow and amount of the adhesive being dispensed. For each application, proper settings—pressure, speed, avoiding adhesive build-up--can avert issues. Learn more on how tank pressure can optimize adhesive usage.
Establishing a routine for filling hot melt tanks keeps hot melt adhesive temperature consistent and prevents char formation, which can lead to plugged filters and nozzles. Consistent hot melt tank filling assures adhesive temperature and reduces downtime to keep production lines moving. Learn how to keep hot melt tanks optimally filled.
