roll-fed labeling machine non-toxic environment protecting look nice and attractive

roll-fed labeling machine

 OPP plastic labels are non-toxic, environment protecting, and look nice and attractive. The technological development of label is rapid. Including o indicating the brand, composition and shelf life, the developers are now working to develop product packaging of low-cost, impact resistance and strong attractive appearance. With the new technology development of shrink packaging system and the emergence of underlying and adhesive of shrink labels, the roll label material OPP plastic label technology provides the processors with a labeling process of low cost, nontoxic and environment protection, low feed consumption and high resolution.

The production process of the roll label material OPP plastic adhesive is short, and its price is affordable. To use the roll label materials such as OPP, BOPP and composite paper to replace the PVC shrink label film; it can achieve more than 30% cost reduction. And it is non-toxic, waterproof. The patterns are not easy to be out of shape. This product is of high class and is the best eco-labels.

With the continuous development of package labeling system, OPP plastic label and adhesive, its price, speed and materials shall need to be more cost effective.

 It is suitable for a variety of bottles of mineral water, beverages, soy sauce, fruit juice, canned food, milk, yogurt and other PET, PP, PE bottles. So the leading manufactures in beverage industry, Coca-Cola and Pepsi-Cola, have changed their labeling methods for large beverage bottles from traditional self-adhesive labels or shrink sleeve labeling to OPP labeling. Thus they can reduce more production costs per day. However, the market price of the beverage has not decreased, so the gross margin for the manufacturers is better than before. The label material OPP is more environmentally friendly and easier recycling than other plastic label materials. Many countries around the world have banned the excessive use of PVC or other plastic materials in food containers. For the non-compliance Manufacturers, they will be asked for additional taxes. Packing material OPP is easier to recycle than other plastic materials, thus many beverage manufacturers have been following this trend. OPP labeling machine can not stick the label the arc or surface of the bottle on. But when the plastic bottle surface has vertical space available for labeling, the labeling effect is more beautiful than sleeve labeling. Because of not shrinking, so the products can be packed directly after labeling.

EVA is a kind of plastic material constituted by the ethylene (E) and vinyl acetate (VA). EVA hot melt adhesive is a kind of polymer free of solvents, without water, 100% solid fusible. It is solid at room temperature.

Its opening hour after application is affected by the indoor temperature and humidity. Generally the workshop temperature should be kept constant at between 15~26 °C. The best humidity should be maintained at about 50%. Therefore, when the hot melt adhesive is applied in many regions, there have been many plastic bubbles in summer and not easy to cure. While in winter, the time for curing and hardening become shorter and it is difficult to cure. In the other areas because of high humidity, the package surface is not fixed. These phenomena are directly related to workshop temperature and humidity. So it is required that: the constant temperature equipment and humidity measuring instrument shall be installed to ensure the proper temperature and humidity. Under high temperature in summer, the temperature for hot melt shall drop about 10°C in order to let the opening and cure time of the adhesive reach reasonable demands. The quantity of the preheated adhesive in the pot shall be proper. When there is too much, the adhesive is over melting, which will make it go bad and ageing, and result in lower viscosity.
