Yes, but it depends on the particle type and usage method. PET (polyethylene terephthalate) film has low surface energy and weak polarity, and ordinary EVA hot melt adhesive particles are prone to “false adhesion” and easy to peel off when directly adhered. To firmly adhere PET, a specialized formula for low surface treatment or a primer (treatment agent) is usually selected.
It is not recommended to directly apply PET to EVA particles used for ordinary books, magazines, and packaging. Sunlife hot melt adhesive has modified or PO particles specifically for low surface energy materials, which have better wetting properties for PET, PP, and PE; Before starting the machine, perform corona or flame treatment on the film to further enhance its adhesive strength.
Q: Why do I use adhesive particles to stick PET and it falls off as soon as I pull it off?
Answer: It is highly likely that the ordinary EVA formula has poor infiltration of non-polar films and needs to be replaced with a specialized formula or coated with a primer.
Q: Do we have to use high temperature to stick PET?
Answer: Moderately increasing the coating temperature can improve flow penetration, but the key lies in the formula, not just heating.
Q: Does Sunlife have ready-made particles that can stick PET?
Answer: Yes, Guangzhou Sunlife Trading can recommend corresponding models and send samples according to your film type.
When encountering difficulties in PET bonding, first send the film sample to Guangzhou Sunlife Trading. Sunlife Hot Melt Adhesive Technology will provide a formula and process combination plan.
The drawing and overflow of EVA hot melt adhesive can affect the appearance of packaging, production pace, and material loss. Explain the troubleshooting approach from five aspects: temperature, glue amount, substrate, opening time, and equipment status, to help packaging and composite processing enterprises establish a more reliable glue selection process. Core KeywordsEVA hot melt adhesive, […]
There are various types of hot melt adhesives with different uses and compositions, generally classified according to their chemical composition and uses. 1、 Polyolefin hot melt adhesive Polyolefin hot melt adhesives include polyethylene hot melt adhesive and polypropylene hot melt adhesive. Polyethylene (PE)is polymerized from ethylene with a small amount of alpha olefin or other […]
The adhesive field is extremely extensive, and its core characteristic is the ability to achieve adhesive function through various mechanisms such as mechanical anchoring and adsorption. Therefore, any substance with such ability can be considered as an adhesive for use. Numerous adhesives have demonstrated cross material bonding capabilities, such as rubber adhesives that can connect […]
Functionality and effectiveness What should be considered when choosing environmentally friendly adhesives? Even at home. For example, if you want to repair a cup, you may use adhesive (a type of contact adhesive), but you will use it in your child’s art project; PVA glue, perhaps using double-sided (pressure-sensitive) tape in the scrapbook. For packaging, […]
