Packaging hot melt adhesiveFor packaging, it is not unfamiliar, not only with high efficiency, but also with high cost-effectiveness. Hot melt adhesive is often used for packaging in cardboard boxes.
Conventional slotted cardboard box (RSC)
Use 1/8 inch beads approximately 1/2 inch from the edge of the flip cover to create durable cardboard boxes. In this case, a T-shaped nozzle can be used to apply double beads. Using a T-shaped nozzle is an effective way to lay double beads and can provide the same results every time. However, if additional strength is required, a standard nozzle can be used and two glue can be placed.
Easy Open Technology on RSC
Hot melt adhesive can be used in various ways to make cardboard boxes easy to open without losing good sealing. These methods can make it easier to reuse cardboard boxes. It is usually recommended to use 1/8 glue to maintain the strength of the cardboard box. You can also use 1/16 glue, but it will reduce the strength of the cardboard box.
Fully Overlapping Carton (FOL)
It can be achieved by placing 1/8 glue on the front and 3 sides, or by laying double glue. For single dispensing applications on FOL cartons, we found that the L nozzle is very convenient. If double-sided adhesive is required, using a T-shaped nozzle is relatively simple.
Hot melt adhesive to save costs
Upgraded batch dispensing, including hot melt dispensing and stitching systems, can save a lot of money. Traditional hot melt adhesives use solid line glue to seal packaging, but this innovative process can use a series of point and line glue, typically using 50% less adhesive.
The yellowing and browning of hot melt adhesive, and even the brittleness of the book back, are mostly caused by the high temperature of the glue pot leading to the thermal decomposition and carbonization of EVA, or repeated heating, insufficient antioxidants, and improper storage. 160-180 ℃ is a safe use zone.
The benefits of handbag glue for food packaging: The use of hot melt glue is widely applied in various industries. Food is one of the areas where your application has experienced significant growth. We are now confronted with increasingly demanding consumers who demand elegant and practical packaging, high-end quality processing, and most importantly, respect for […]
Hot melt adhesive granulesIs it environmentally friendly or toxic? Legitimate hot melt adhesive particles themselves are thermoplastic polymers that are solid, non-volatile, and insoluble in water at room temperature, making them relatively safe adhesive materials. Whether it is “toxic” mainly depends on the formula and high-temperature usage method. Looking at safety from three aspects raw […]
Color does not represent good or bad Many customers see Hot melt adhesive granules If it turns yellow, I’m worried about poor quality. In fact, the color mainly comes from the resin grade and whether anti-oxidation and thickening agents are added, and has no direct relationship with whether it is sticky or not. Where does […]
