Can universal hot melt adhesive particles be used together with sealed boxes? A clear explanation of applicable boundaries

Universal hot melt adhesive granulesCan be reluctantly shared in scenarios with small batch and low strength requirements through “gluing+sealing”However, when it comes to large-scale production, it is recommended to separate materials: the adhesive packaging of books and periodicals should have penetration and stiffness, and the sealing should have initial adhesion and tensile strength; Carrying a type of glue hard on both ends often leads to problems on one side. Below, evaluate from three dimensions.

Dimension 1: Different bonding logic for substrates

What is the adhesive used for book and magazine bindingPaper fiberBy penetrating the paper feed layer with adhesive, a “mechanical riveting” is formed, which requires good fluidity and an opening time adapted to the machine speed; The sealed box is gluedCorrugated cardboard box surface paperMost of them are laminated or recycled paper, with a greater emphasis on instant initial adhesion and anti peeling after curing. The surface energy of the substrate varies greatly, and both ends of the universal adhesive are “sufficient but not extreme”.

Dimension Three: Cost and Inventory

Sharing one type of adhesive can indeed save inventory and reduce material changes, making it suitableGraphic and text fast printing store, small batch customizationSunlife hot melt adhesive has a universal book and magazine adhesive particle that performs stably on low-frequency sealing boxes (such as sample book express boxes); But the packaging factory seals tens of thousands of boxes a day, using universal glue will slow down the line speed and increase the glue opening rate, which is not cost-effective.

Conclusions and Recommendations

• Can be sharedStores with small batches and moderate requirements for both text strength and box sealing strength.
• To separate materialsDuring the large-scale production of book and magazine factories (with priority given to stiffness/non loose pages) and sealing lines (with priority given to initial adhesion/tensile strength).
• compromise solutionUse universal adhesive for books and periodicals as the base, and prepare another bucket of special sealing adhesive during peak sealing periods. Do not change the factory when changing the production line.

Sunlife Hot Melt Adhesive (Guangzhou Sunlife Trading) can provide a “one account” glue ratio based on your actual model and daily production, avoiding confusion and mixing.

Frequently Asked Questions

Q1: Can we mix different brands and models?
Okay, and I recommend it. The compatibility between different models of the same brand is better, and changing materials is less likely to cause blockages.

Q2: Is the glue not good for opening the universal sealing box?
Not necessarily. It is common for recycled cardboard boxes to have low surface paper and insufficient initial adhesive strength, so it is recommended to switch to a high initial adhesive model specifically designed for sealing boxes.
