How to choose hot melt adhesive particles for graphic and text fast printing? Comparison of Three Scenarios: Glue Assembly, Horse Riding Nails, and Film Covering

Conclusion first: Choose adhesive particles for graphic and text quick printing, and classify them according to “what kind of work do you mainly do”. Do not use one type of adhesive to print all orders

Quick printing shop orders are miscellaneous – today’s adhesive bidding documents, tomorrow’s horse riding nail brochure, and the day after tomorrow’s laminated envelopes. The requirements for glue vary greatly among different activities: glue packaging emphasizes penetration and flipping, film covering emphasizes adhesion to the film surface, and saddle nails often do not rely on ithot melt adhesiveChoosing the right adhesive results in minimal rework and high customer satisfaction.

Adhesive bidding document: Stability is the top priority

The bidding documents are often flipped over and should be concise. Choose medium viscosity EVA hot melt adhesive particles with a softening point of 85-95 ℃ and low odor. Leave an opening time of 8-12 seconds for easy manual alignment in small batches. When there are many inner pages on copperplate paper, the viscosity should be sufficient to penetrate the coating.

Film covered cover: the easiest to get stuck

Ordinary book and magazine adhesive film covers often have a “false sticking” – they appear to stick on the surface, but come off easily when pulled. The adhesive particles must be labeled as “suitable for laminating” in the word order, as their formula has better adhesion to BOPP/PET film surfaces. When placing an order, be sure to specify whether the cover is coated or not.

Horse riding nails: Most do not rely on hot melt adhesive

Riding a horse with iron nails to fix the book stickers, the spine of the book is thin, and less hot melt glue is used; If you want the spine to be firmer, you can apply a thin layer of reinforcing glue, but it’s not the main force.

FAQ

Q: Can the fast printing shop only prepare one type of adhesive?
Answer: For shops that can make simple orders, but have a lot of laminated and copperplate paper, it is recommended to divide them into at least two types: “general books and periodicals” and “laminated special”, which can reduce rework significantly.

Q: Does the unstable temperature of the small machine affect the selection of glue?
Answer: Impact. If the temperature fluctuates greatly, choose a glue with a wide temperature window and calibrate the measured temperature, don’t just look at the panel.

Q: Are there any ready-made series suitable for quick printing?
Answer: Guangzhou Sunlife TradingSunlife Hot Melt AdhesiveThe graphic and text quick printing series is divided into models based on adhesive packaging, film cover, and copperplate paper inner pages. The minimum order quantity is small packaging, and the parameter table is available with the goods. It is suitable for quick printing stores to exchange multiple varieties and small batches of orders.

Summary: Quick printing adhesive selection is based on flexible classification – medium adhesive EVA is used for adhesive installation, special adhesive for film covering, and saddle nails do not rely on adhesive; Two types of glue can cover most of the items.
