What is Namitac solventless laminating adhesive?

What is solventless laminating adhesive?

Namitac solvent-free (solventless (lamination adhesives contain 100% active ingredients and do not carry water or solvents. These laminate adhesives are commonly used in flexible packaging applications. Specifically, they are two-component adhesives consisting of isocyanate and polyol that react to form polyurethane after mixing. solventless laminating adhesives save the production costs of laminating machines by eliminating the need for ovens and drying tunnels to remove water or solvent carriers in water-based or solvent-based adhesives.

Solvent-free laminating adhesives (solventless laminating adhesives) are applied to base layers such as films or foils using solvent-free laminators that can transfer the adhesive through rubber and metal cylinders. The coated substrates are subsequently bonded to a secondary substrate under the pressure and temperature of the nip cylinder to form the laminate. These wrappers may contain multiple layers of laminate used to make flexible packaging.

Flexible packaging made with solvent-free laminate adhesives are used in a variety of food and beverage packaging applications and meet a wide range of FDA regulations. For example, several options or grades of solvent-free adhesives are offered with suitable adaptations for semi-prepared food, hot filling, boil-in-the-bag, microwave and frozen food packaging.

Namitac solventless laminating adhesives are produced and supplied in different grades to meet the needs of a wide range of customers.

Various grades of Namitac solventless laminating adhesive are designed for the following applications:

• solvent-free laminating adhesives for laminating at high speeds up to 400 meters per minute.
• solvent-free laminating laminate adhesives for paper-to-film lamination or paper-to-foil lamination.
• solvent-free laminating adhesives for laminating all types of films and foils with different structures such as polyester-polyethylene-BOPP and all types of metallized films.
• solvent-free laminating adhesives with a high mixing interval to prevent delamination due to mixer error.
• solvent-free laminating adhesives with wrapping drying properties.
• Two-component solvent-free laminating adhesives with product softening properties.
• solvent-free laminating adhesives with high resistance in pasteurized products.

Solvent-based laminating adhesive

High performance Solvent-based laminating adhesives account for approximately 15% of the highest demand flexible packaging units. Some common products in this packaging category include laundry detergents with aggressive ingredients, medical applications, pet foods, and baby meals that are filled under sterile conditions.

When you are faced with a specific set of packaging requirements, choosing the most suitable raw materials for laminating adhesive is critical to achieving the most effective solution. Taknam Keyhan Polymer Solvent-based laminating adhesives have high adhesive strength, suitable viscosity with special characteristics and can be used for a number of applications and flexible packaging substrates.

Taknam Solvent-based laminating adhesives are also designed for non-food applications (detergent packaging, etc.) and indirect food applications.

These products have a short curing time, excellent initial adhesion and a low delay between the time of lamination and cutting. Taknam Keyhan Polymer’s sales and R&D departments can provide guidance and support to ensure that your food packaging staff is trained and supported to implement your specific programs.

The unique advantages of Namitac solvent-free laminating adhesive

Taknam Keyhan Polymer offers innovative and high-performance laminating adhesives for flexible packaging:

Taknam’s solvent-free lamination adhesive products are environmentally friendly and provide an economical and low-cost adhesive for high-speed production lines. These products are ideal for flexible packaging with general applications such as film-to-film and film-to-metal.

Namitac solvent-free laminating adhesives offer a unique adhesion with slow pot life and fast curing, which can be suitable for food packaging process problems. Laminated samples with Taknam’s laminating adhesive do not contain aromatic amines. Aromatic amine is a substance that is produced as a result of adhesive penetration to the surface of the film in reaction with air humidity, and it is highly carcinogenic. Samples laminated with Namitac’s laminating adhesive do not contain such chemicals and are completely suitable and safe for food packaging.

Specialized adhesives and green adhesive

The demand for packaging materials is becoming more and more critical due to increasing awareness of product safety requirements worldwide. Flexible packaging laminates are one of the main packaging materials today and must meet the expectations of converters and end users. Laminating adhesives are a key component in any laminate structure. All kinds of Teknam’s laminating adhesives are designed to meet these vital expectations. Teknam’s hybrid lamination and polyurethane adhesives have a wide range of adhesives for solvent-based and solvent-free applications. Teknam’s technical experts work closely with suppliers and customers of brand owners to design products with appropriate specifications.

Vegetable oil-based adhesive

This adhesive has two components. The first component is a prepolymer made from a prepolymer. After making this product, the viscosity, color and percentage of NCO of the desired product are tested. This product is packed in a plastic barrel. The second component is a polymer mixture called polyol. The tests of this component are viscosity, color and hydroxyl number.

The superiority of vegetable oil-based adhesives over synthetic adhesives is the use of non-renewable petroleum resources instead of petroleum-based resources. On the other hand, the use of materials with less pollution in the working environment is another advantage of this product. The viscosity of our adhesive sample is very low and at the level of expensive polyether adhesives. Depending on the customer’s order, we can change the viscosity of the adhesive while keeping other properties constant.

Storage conditions

Laminating adhesives should be stored at room temperature in closed containers and in a dry place at a temperature between 5 and 30 degrees Celsius. If the temperature of its storage or transportation goes above 30 degrees, it should be kept at room temperature for 4 to 6 hours so that its activity becomes normal again. Exposure to direct sunlight should also be avoided. The shelf life of Namitac laminating adhesives is stable for 12 months provided they are kept under the above conditions.
