In the field of printing and packaging, surface finishing is one of the components of the entire process design. For printed matter or packaging boxes, surface finishes are important both in terms of giving the product a professional and high-quality image, and in maximizing the durability and attractiveness of the product. The combination of plastic film and cardboard can combine images with attractiveness, protection and strength. The film not only enables the print to have a high-gloss or matt surface, but also ensures that the print reaches the application site safely.
Akzo Nobel Industrial Finishes offers a full range of adhesives for film coating to meet a variety of application needs. One of the goals of the company's paper coating R&D department is to produce adhesives for films with higher bond strengths. This goal promoted the development of Nubond Instant, a high-performance, “transient†adhesive that was specifically developed for dry compounding. It is suitable for coating a small thickness, high gloss or matt, pretreated OPP film on the surface of a printed or unprinted paper-based material.
Nubond Instant Adhesives show an ultra-fast development (almost "instantaneous") in adhesive strength, enabling subsequent processing (such as embossing, crimping, indentation and folding) to be performed immediately. The use of this adhesive shortens the "drying time" that is too long, which greatly increases the processing speed of the product. According to CHIP regulations, the non-volatile components of Nubond Instant Adhesives are considered harmless and do not contain any isocyanates.
Nubond Instant is a one-component solvent-based adhesive that does not require the addition of a curing agent. The company can supply Nubond Instant adhesives using various mixed solvents as needed. Adhesives also have the following characteristics:
â— Relatively stable with sensitive Reflex Blue pigments â— Resistant to tropical conditions after processing â— No lifespan â— Dryable by heated rollers or hot tunnels â— Reverse roller/blade coating technology

Medical grade polymers are a type of plastic material that are specifically designed and manufactured to meet the stringent requirements for use in medical applications. These polymers offer several advantages over traditional materials such as metals, ceramics, and glass in terms of their biocompatibility, versatility, and cost-effectiveness. Some of the key advantages and applications of medical grade polymers include:
Biocompatibility: Medical grade polymers are designed to be biocompatible, which means that they do not cause an adverse reaction or toxicity when they come into contact with living tissue. This property makes them ideal for use in medical implants, drug delivery systems, and other medical devices.
Versatility: Medical grade polymers are highly versatile and can be molded into a variety of shapes and sizes. They can also be modified with different additives to enhance their properties such as flexibility, strength, and thermal stability. This versatility allows them to be used in a wide range of medical applications.
Cost-effectiveness: Medical grade polymers are generally more cost-effective than other materials such as metals and ceramics. This is because they can be manufactured in large quantities using injection molding or other high-volume production techniques.
Resistance to corrosion and wear: Medical grade polymers are highly resistant to corrosion and wear, which makes them ideal for use in medical devices that are exposed to bodily fluids and other harsh environments.
Some of the key applications of medical grade polymers include:
- Medical implants: Medical grade polymers are commonly used to manufacture implants such as artificial joints, dental implants, and pacemakers. These materials provide a high level of biocompatibility and can be easily molded into the required shape.
- Drug delivery systems: Medical grade polymers are also used to manufacture drug delivery systems such as capsules, pumps, and patches. These materials can be designed to release drugs at a controlled rate, which can improve their efficacy and reduce side effects.
- Medical devices: Medical grade polymers are used to manufacture a wide range of medical devices such as syringes, catheters, and tubing. These materials are highly versatile and can be designed to meet specific requirements such as flexibility, strength, and durability.
- Packaging: Medical grade polymers are also used to manufacture packaging materials for medical devices and pharmaceutical products. These materials provide a high level of protection and can be designed to meet specific requirements such as moisture resistance and gas permeability.
Overall, medical grade polymers offer several advantages over traditional materials in terms of their biocompatibility, versatility, and cost-effectiveness. These properties make them ideal for use in a wide range of medical applications.
