EVA hot melt adhesiveWhat are they made of and can they be recycled? The difference between biodegradable and bio based packaging follows a global trend where consumers want to produce and purchase more environmentally friendly products.
The awareness and recognition of more environmentally friendly and sustainable packaging materials (such as reusable, biodegradable, etc.) are growing, but for some people, evaluating the impact of adhesives on the sustainable development model of the industry is often confusing and difficult. It is a small yet important component of modern packaging.
Most EVA hot melt adhesive is typically made from a combination of polymers, resins, waxes, and functional additives, making it a thermoplastic. Thermoplastic is a substance that turns into plastic when heated and hardens when cooled, making it easy to recycle, but some eventually become microplastics in marine environments. This is one of the biggest challenges facing the adhesive industry.
EVA hot melt adhesive is an essential part of packaging manufacturing, and most modern recycling and waste management measures ensure that the glue in these materials does not enter the marine environment.
Most hot melt adhesives are not easy to recycle, but their compatibility with recycling is crucial – they must not affect the recycling ability of the bonded products. Some adhesives make this process more difficult, forming a substance commonly known as a “sticky substance” because they can soften and form gelatinous balls during the pulping process, but usually these do not attract much attention and are an acceptable part of the recycling process.
Unused hot melt adhesive can be recycled into similar products, although not always feasible, if the adhesive can be removed from its application surface, it can also be recycled into similar product types. When producinghot melt adhesiveAt that time, there was almost no material waste, and any unused adhesive usually needed to be reprocessed.
Regarding the viscosity and stickiness of hot melt adhesive, many customers will always ask if your hot melt adhesive is strongly adhesive, which means “sticky”. Without specifying what material to stick, it is not possible to directly determine whether the hot melt adhesive is strong or not. Hot melt adhesive is only suitable or not, […]
High temperature resistant hot melt adhesive for books and magazines is mainly based on polyamide resin, so high temperature resistant hot melt adhesive is also known as polyamide hot melt adhesive. Polyamide resin is a linear thermoplastic resin with a large number of repeated amide groups on the molecular main chain. Compared with other thermoplastic […]
You will find hot melt adhesive everywhere in your daily life. From the furniture you sit on to the corrugated cardboard boxes containing mail at the local post office, it is not difficult to find items bonded with this popular adhesive. Companies that work with wood, fabric and foam plastics, shoe manufacturers, bookbinders and plastic […]
Why is it easy to clump in summer When the temperature is high,Hot melt adhesive granulesThe surface will slightly soften and adhere to each other, with severe cake formation throughout the bag, blocked feeding ports, and uneven adhesive glue. This is not a quality issue, the main reason is that the “storage temperature” and “softening […]
