Extrusion Pe Machine Coating With Kraft Paper
Extrusion Pe Machine Coating With Kraft Paper
The Kraft paper bag is a common type of packaging used for many items.extrusion pe machine coating with kraft paper This paper has a very high strength and is suitable for use with food items as well as dry goods. It also has good barrier properties to prevent moisture from affecting the contents. It can be coated with a variety of materials, including polyethylene (PE), to improve its barrier properties and heat sealability.
The kraft paper bag can be printed with a wide variety of designs and colors to suit the item being packaged. It can be made with a flat bottom, which allows it to stand up when empty or filled, or with a gusset, which provides an expanded section that makes the bag able to carry heavier and larger items. It can also be laminated with PE to provide added protection, for example, against puncture and tearing.
To make a kraft paper bag that is suitable for PE coating, the kraft paper must be treated to improve its water resistance and to provide a better barrier against oil and grease. The treatment is typically carried out during the manufacturing process, but it can also be performed as a separate 'off-line' treatment.
In order to achieve this, the kraft paper must be treated with an additive that reacts with its surface and changes its physical properties. A number of different compounds are available for this purpose, but it is important that the chemical used does not damage the paper itself, which could affect the overall performance of the finished product.
A paper/aluminium foil/nonwoven/paper extrusion coating laminating machine 1m-3m is designed for multiple application areas. It has a shaftless unwinder with an auto-splicing system and a web-guide device to ensure that the paper is fed into the machine correctly. The extruder capacity, traction (molding), line speed and meters counter are all controlled by an imported PLC programmable controller.
The process of extrusion pe machine coating with kraft paper uses a special combination of raw material and equipment that gives the finished product superior properties compared to ordinary paper. In addition to a smooth surface, the result is a film that is ten times stronger and has improved water resistance and oil resistance. The process can be used to manufacture a variety of products, including bags and wrappers for foods, and is extremely cost-effective and environmentally friendly.
Kraft paper is an industrial paper that can be glazed and coated to add strength, waterproofness, or other functional properties. It can be used to make paper cups, trays, or boxes for food and drink, as well as cardboard cartons and wrapping for various products. It can also be coated with a variety of plastics to produce laminates that combine the best properties of both materials. It is particularly useful in applications where the end-use of a product requires enhanced barriers against oil and grease, for instance, food and paper package stock.
