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.
hot melt adhesive pelletsAre you afraid of ultraviolet rays? Hot melt adhesive particles are based on high molecular weight materials such as EVA, PO, PA, etc. These materials undergo photo oxidative degradation under long-term UV irradiation – molecular chain breakage, decreased cross-linking degree, resulting in yellowing and brittleness of the adhesive layer, and decreased bonding […]
Book bindingHot melt adhesive granulesHow to calculate the dosage? Many book and magazine factories purchase hot melt adhesive granules based on “feeling”, resulting in either material shortage, production stoppage, or stockpiling and occupying warehouses. In fact, the dosage can be calculated very accurately: the glue consumption per book ≈ the spine coating area x the […]
For most terminal packaging operations, adhesive carbonization is usually the main cause of most downtime events. Once EVA hot melt adhesive carbonization occurs, it will be difficult to clean thoroughly without taking extreme measures. Even after flushing, charcoal may still stick to narrow corners and continue to cause issues that affect normal operating time and […]
EVA hot melt adhesive material is a thermoplastic adhesive that is very different from ordinary cold glue. According to its characteristics, the following points must be grasped and paid attention to during use: 1、 Understand and master the various models and technical performance (parameters) of EVA hot melt adhesive. Different types of hot melt adhesives […]
