Hot Melt Adhesive and Soft Plastics：Can They Stick Together？​

Hot melt adhesive gets along well with soft plastics—sticking them is usually no problem, as long as the plastic doesn’t contain ingredients that react badly with the adhesive.​

Common Soft Plastics Hot Melt Adhesive Handles​

Many soft plastics on the market bond easily with hot melt adhesive. These include PE, PP, PS, PVC, PC, PU, and PET—materials used in countless products.​

You’ll find hot melt adhesive at work in everyday items:​

• Parcel express bags (made of PE) use hot melt pressure-sensitive adhesive to seal their flaps.​

• PVC edge strips on office desk boards are bonded to panels with granular hot melt glue.​

From small plastic parts to larger items, hot melt adhesive is a go-to for sticking these materials.​

Matching Hot Melt Adhesive to the Job​

Hot melt adhesive comes in multiple models, each suited to different soft plastic applications. This variety means it can handle bonding plastics in almost any way needed, without being limited by specific techniques.​

While sticking soft plastics is generally easy, occasional issues usually stem from external factors: too many impurities on the plastic surface, incorrect gluing methods, or a mismatch between the adhesive’s traits and the production process. These don’t change the fact that hot melt adhesive and soft plastics are a good match.​

A Quick Tip for New Users​

If you’re trying hot melt adhesive with soft plastics for the first time, test the bond first. This lets you check if the adhesive meets your needs—though it’s rare to find a soft plastic that hot melt adhesive can’t stick to, unless there’s an incompatible ingredient.​

Hot melt adhesive is a reliable choice for bonding soft plastics. With the right model and proper application, it creates strong, lasting bonds in everything from packaging to everyday plastic products.​
