Why Extrusion Coating And Lamination Are Widely Used?

Why Extrusion Coating And Lamination Are Widely Used?

Extrusion coating and laminating are the processes of converting that allow different types of substrate materials to combine to obtain a single compound structure. The materials involve are plastics, carton board, paper, or aluminum foils. There are different requirements for people. The machines of extrusion coating and lamination are designed in a way to fulfill the requirement. For instance, many industries require a paper cup extrusion lamination machine of high-quality manufacturing for various purposes. The extrusion coating is a process where molten plastic is applied and chilled subsequently to form an extremely thin and smooth layer of uniform thickness.to laminate a plastic film or metal foil, the molten plastics are used as an adhesive.

The mono extrusion coating and laminating machine is also very famous in modern industries. Its high-speed version adopted more advanced equipment like auto water temperature control device and auto air gap adjustment unit.

Purpose of extrusion coating and lamination:

The extrusion coating and lamination process are used for different purposes or to achieve:

  • Heat seal ability
  • Protection of moisture
  • Resistance of grease
  • The barrier to oxygen, aroma, vapor, etc.
  • Sales appeal for instance shiny surface

Sales appeal:

The extrusion coating and laminated paperboard usage are high as it provides outstanding promotional benefits of visual appeal and great customer handling. By extrusion coating and high gloss chill roll specifically, high gloss is created. Moreover, it creates a metallic effect with aluminum foil or metalized polyester film. These processes and materials provide a high quality of tactile sensations and luxury which the consumer links with high value packaged products.

Functional coating:

In general, the most suitable for the packaging of dry products is paperboard. Extrusion coating or laminations add thin plastic layers to the paperboard. The plastic coating can provide grease and moisture resistance and heat resistance where needed. Aluminum lamination provides packages with barriers to moisture, light, grease, and gases. This is often coats to provide heat sealing abilities and product safety.

Applications:

The lines of extrusion coating and laminating are custom-built and can be configured for different applications which include aseptic drink containers, toothpaste tubes, liquid packaging, industrial wraps, medical packaging, and insulation backed materials. These also use in plastic-coated tablecloths, sacks for products, cereal grain, and dry chemicals. Extrusion coater laminators provide a combined substrate and the complement elements which are very difficult to separate. The combined substrates inherit enhanced properties of physical and barrier protection performance from the components.

Some most common plastic products by extrusion coating and lamination:

  • Instant noodle bags
  • Polypropylene knitted bags
  • Paper cups
  • Snacks bags
  • The packet of ketchup
  • Strip foil

Characteristics:

This process operation uses high melt temperatures to lower the viscosity. This feature of extrusion coating and lamination improves the thickness of coating uniformity and adhesion. These processes are highly versatile which allow combining various substrates such as al. foil, paper, non-woven, plastic films, etc. of different thickness. With a high-quality level of combining characteristics of each substrate and thermoplastics material used to form a composite structure of different materials.
