Food Grade PE Coated Paper Cup Raw Material | Dihui Paper

Food-grade PE coated paper has become one of the most widely used materials for disposable food containers because it provides strong barrier protection and stable forming performance.As a manufacturer specializing in paper cup raw material, Nanning Dihui Paper Products Co., Ltd. provides a range of products designed to support different stages of paper cup and food packaging production. From coated paper rolls to ready-to-use fan sheets, these materials are developed to meet the needs of both large manufacturers and smaller converters.

Food-Grade PE Coated Paper: A Reliable Barrier Material

PE coated paper is produced by laminating a thin layer of polyethylene onto the surface of base paper. This coating enhances the paper’s resistance to moisture, grease, and heat while maintaining the natural rigidity required for cup forming.

Depending on the intended application, different coating structures may be used.

• Single PE coated paper consists of base paper laminated with one PE layer. It is commonly used for hot paper cups where moisture protection is required on the inner surface.

• Double PE coated paper includes PE coating on both sides of the paper. This structure is often chosen for cold drinks because it helps prevent condensation from affecting the outer surface.

• Composite coated materials, such as aluminum foil or gold foil laminated paper, are used in specialized packaging that requires stronger barrier properties.

These materials are typically supplied in roll form so that manufacturers with their own printing or die-cutting equipment can process them according to their production needs.

PE Coated Paper Rolls

PE coated paper rolls are one of the most commonly used raw materials in the paper cup industry. The paper is processed through extrusion coating, where polyethylene is applied evenly across the paper surface.

The basic production structure can be summarized as follows:

• Single PE Coated Paper Roll
  Base Paper + PE

• Double PE Coated Paper Roll
  PE + Base Paper + PE

• Gold Foil Laminated Paper
  Base Paper + PE + Gold Foil + PE

• Aluminum Foil Laminated Paper
  Base Paper + PE + Aluminum Foil + PE

Many manufacturers prefer to purchase coated rolls because they already have their own printing or die-cutting lines. In such cases, coated paper rolls provide flexibility while maintaining consistent quality.

At Nanning Dihui Paper Products Co., Ltd., coated paper is available in 150–320 gsm, allowing customers to choose the appropriate thickness depending on the cup size or packaging application.

Printed Paper Rolls

For brands that require customized designs, printed paper rolls are often the next step after coating.

Flexographic printing is widely used for food packaging materials because it supports high-speed production and environmentally friendly inks. In this process, flexible resin plates transfer water-based ink through an anilox roller onto the paper surface. Compared with some traditional printing methods, flexographic printing generally produces lower VOC emissions and is well suited for food-grade packaging.

Dihui Paper currently operates two printing machines, capable of producing designs with up to six colors. Both flexographic printing and offset printing options are available, giving customers more flexibility when selecting printing styles or visual effects.

The basic process for printed rolls is:

Printed Paper Roll = PE Coated Paper (or Base Paper) + Printing Plate + Ink

Because printing plates are customized according to the design pattern, plate confirmation is usually required before production begins.

Paper Cup Fan

Paper cup fan are semi-finished materials that can be fed directly into paper cup forming machines. They are widely used by factories that want to reduce processing steps and improve production efficiency.

These fan sheets are produced through die-cutting processes that shape the coated or printed paper into the curved structure required for cup walls. After forming, the paper cup machine can easily seal the side wall and attach the bottom paper.

Typical products include:

• Paper cup fan sheets

• Paper bowl fan sheets

• Lunch box or food container sheets

The general production process is:

Fan Sheet = Coated or Printed Paper Roll + Die Cutting + Waste Removal

One advantage for customers is that die plates can be customized according to cup size specifications.

Bottom Paper Rolls

In addition to side wall materials, paper cups also require bottom paper for sealing the base of the cup.

Bottom rolls are produced by slitting coated paper rolls into narrower strips that match the size requirements of paper cup machines. Once cut into discs during production, they are attached to the cup body to form a leak-resistant bottom structure.

The basic process is simple:

Bottom Paper Roll = PE Coated Paper Roll + Slitting Process

Having consistent bottom paper quality is essential for stable cup forming and reliable sealing.

PE Coated Paper Sheet

Another commonly supplied material is sheet paper, which is cut into flat sheets instead of rolls. The process can be summarized as:

Sheet Paper = Base Paper + Sheet Cross- Cutting Process

Paper sheet is typically used for offset printing, resulting in more exquisite designs.

Supporting Flexible Production Needs

In today’s competitive packaging market, manufacturers often look for suppliers who can provide both stable materials and flexible customization options. For this reason, many buyers prefer to work with suppliers who can support various stages of production—from coated rolls to ready-to-form fan sheets.

At Nanning Dihui Paper Products Co., Ltd., the focus has been on providing practical solutions for paper cup and food packaging manufacturers. In addition to supplying raw materials, the company also offers free design support and sample testing, which can help customers evaluate materials before full-scale production.By combining different coating structures, printing options, and paper brands, manufacturers can select materials that match their production equipment and final product requirements.
