plastic cores for paper rolls

Thermal paper often employs a variety of core types and sizes to fully the needs of various printing equipment and applications. The following are some examples of popular thermal paper cores:

• 1/2 inch (12.7mm) core:
  • A tiny core that is commonly found in small mobile printers, portable label printers, and certain small receipt printers. It is appropriate for narrow-width thermal paper rolls.
• 1 inch (25.4mm) core:
  • One of the most popular core sizes, it is commonly used in ordinary receipt printers, POS systems, label printers, and general printer applications. It is compatible with a variety of thermal paper widths.
• inch (76.2mm) core:
  • This bigger coreis typically used in high-speed, high-capacity printing equipment such as industrial label printers and some point-of-sale (POS) systems.
• Other custom core sizes:
  • Custom core sizes can be developed to satisfy non-standard thermal paper roll parameters based on the needs of special applications.

• Cardboard core:
  • One of the most prevalent forms of cores is cardboard core. It is often constructed of multi-layer cardboard and has a high level of structural strength and stability. This type of core is frequently recyclable and eco-friendly.
• Plastic tube core:
  • A plastic tube core is often constructed of a strong plastic material that is both durable and watertight. As a result, the plastic core performs well in some unique situations, such as damp or water-sensitive circumstances. They are also extensively utilised in food packaging and other waterproofing applications.
• Some tube cores are composed of paper composite, which combines the strength of cardboard with the durability of plastic. In some situations, this material structure may give higher performance.
• Other materials:
  • In addition to the conventional core materials described above, there are other cores constructed of unusual materials, such as alloy cores and high-strength materials designed for specialised requirements.

• heat resistance: polyester plastic has a good high temperature resistance, can be used at higher temperatures.
• chemical resistance: polyester plastic has good resistance to most chemicals.
• abrasion resistance: polyester plastic has good surface hardness and abrasion resistance.
• sealing: polyester plastic has good sealing performance, which can avoid moisture and oxidation of thermal paper core.
• easy to process: polyester plastic can be processed into different shapes and specifications of products through injection molding, extrusion and other processes.

Thermal paper tube core plastic manufacturing process mainly includes the following steps:

• material selection: choose the appropriate polyester plastic particles as raw materials.
• plastic extrusion: the polyester plastic particles heated and melted through the extruder extrusion molding.
• Plastic molding: the extruded plastic material is cut into tube cores of different lengths according to the requirements.
• Micro-perforation: Cutting holes or micro-perforations on the outside of the tube core.
• surface treatment: the surface of the tube core coating, printing and other treatments.
