In the past, the composite packaging materials required for flexible packaging have traditionally used solvent-based adhesives. However, as environmental protection regulations have increasingly stringent requirements for solvent-based adhesive systems, manufacturers are actively seeking alternative products in European composite films. Manufacturers began investing in new types of equipment and switching to solventless adhesives; a significant portion of manufacturers in North America adjusted existing equipment to accommodate the use of water-based adhesives.
ROHM HRRS, one of the world's largest manufacturers of fine chemicals, recently introduced the water-based RobondTM series of dry composite adhesive products. The product is available in both single-component and two-component formulations and can be adapted to meet the needs of low-to-medium demand and special function requirements. Robond L-series water-based adhesives have unique universal applicability, excellent performance, environmental benefits, productivity improvement, and lower price than solvent-based adhesives. As a result, the product has rapidly become a favorite of composite manufacturers. .
The Robond L series waterborne adhesives have the following features:
1. Can bond a variety of substrates: paper, plastic, film, aluminum foil, metal film, etc., especially bonded metal film is particularly good.
2. In the back printing process, this product can be used in conjunction with a variety of solvent-based, water-based and UV-resistant ink systems, giving the product a clear appearance.
3. RobondL water-based adhesives also ensure adhesion at typical low temperatures, and also reduce curling, curling, and extension problems.
4. RobondL's water-based adhesives have high wet strength and have a distinct advantage over solvent-based and solvent-free adhesives in the in-line laminated composite process after extrusion. Solvent-based adhesives are prone to fire and solvent-free wet strength is low.
5. Short curing time can quickly reach the strength requirements, thereby improving the processing efficiency and production speed, the operating speed can reach 300m/min.
1. Sit Stand Workstation Lift freely, can stand can sit alternate office, stand sit alternate do not hinder busy business at hand.
2. It's easy to operate, just press the button to achieve the purpose of alternate standing and sitting.
3. Memory function storage: that is, the user can adjust the function key to a suitable height according to his own height, and adjust the function key to a fixed position to facilitate the fixed position and use.
4. The appearance is simple and generous, which is in line with the international office trend and different from the traditional desk style which is dull and not easy to move.
5. It is beneficial to the physical and mental health of office workers, increases work efficiency, enlivens the workplace atmosphere and makes the workplace atmosphere more active.
