EVA hot melt adhesives are inexpensive and versatile in the industrial sector – but which commercial items are manufactured with hot melt adhesives commonly used? Here are the six most common applications in manufacturing:
1) Quick assembly, recyclable cardboard box
The transportation packaging industry is a large user of EVA hot melt adhesive seam sealing. Packers and manufacturers use it to create strong bonds on box edges, envelopes, top seals, lid fillers and product-in-box containers.
2) Binding printed books and magazines
How are pages in modern publications held in place without traditional lock lines? Thanks to the use of EVA hotmelt for books, fully printed books can be bound quickly, inexpensively, and in a way that will stand the test of time – all without damaging the pages.
3) Paste product labels and covers
Sometimes, manufacturers need to put a pre-printed external label on their box or on the product itself. For some products, such as bottles and cans, it is nearly impossible to print directly on the surface. Hot melt adhesives can attach strong adhesive labels to virtually any substrate and surface shape.
4) Making hygienic disposable medical supplies
Bandage, tampon and medical pad manufacturers all routinely use hot melt adhesives to create safe, sterile, degradable seals. Precise hot melt connections have helped biomedical experts create seamless, metal-free absorbent disposables that remain sterile, hygienic and safe to use on human skin.
5) Glue non-conductive electronics inside
A serious problem with hermetic electronics is that the plastic molding and metal need to fit together without the risk of conductive bridging or parts falling apart. While screws can bridge the gap, hot melt glue can also help. Melted contact seals are used around finer circuit boards and machine cladding to create layered “layers” to save space and ensure build strength.
6) Lock the woodwork together
When it comes to wood products, screws and locking joints are not the only options on the market. Special grades of molten hot melt adhesives can create durable, long-lasting bonds that seal parts together or reinforce existing woodwork for greater integrity in the finished wood piece.
