PE-Coated Paper for Food Packaging
Casperg PE-Coated-Paper Manufacturing Advantages
1. Coating Structure Matched to the Final Application
Casperg supplies single-side and double-side PE-coated paper according to the intended food, container structure and storage conditions. Single-side PE-coated paper is commonly selected for hot-drink cups and selected food containers, while double PE-coated paper for cold-drink cups and ice cream packaging provides additional protection against external moisture and condensation.
2. Base Paper and PE Coating Weight Clearly Specified
Incorrect or incomplete grammage information can result in insufficient stiffness, sealing problems and unexpected purchasing costs. Each PE-coated paper quotation identifies the base-paper grammage and PE coating weight separately, helping buyers compare specifications accurately and select the right material structure.
3. Reliable Heat-Sealing and Converting Performance
The base paper, PE coating and surface treatment are selected to support printing, die-cutting and heat sealing. Consistent specifications help PE-coated cupstock paper run more smoothly on paper-cup and food-container forming machines, reducing sealing failures, paper breaks and production waste.
4. Custom Roll Dimensions for Your Equipment
Casperg provides custom-width PE-coated paper rolls based on the buyer's printing, slitting, die-cutting or forming equipment. Roll width, diameter, core size and winding direction can be confirmed before production to reduce trimming loss, machine adjustment and unnecessary downtime.
5. Jumbo Rolls, Slit Rolls and Custom Sheets Available
Buyers can source PE-coated paper in jumbo rolls, machine-ready slit rolls or customized sheets. This allows paper-cup factories, food-container converters and packaging distributors to select the format that best fits their production capacity, storage conditions and downstream processing.
6. White Cupstock and Kraft Paper Options
Available base-paper options include white cupstock and kraft paper, subject to the required application. PE-coated kraft paper for food packaging supports a natural appearance, while white PE-coated cupstock offers a clean surface for branded paper cups, bowls and takeaway containers.
7. Samples and Specification Verification Before Bulk Orders
Existing samples or trial material can be arranged according to specification availability. Buyers can evaluate stiffness, coating coverage, printability, heat-sealing performance and machine compatibility before placing a bulk PE-coated paper order, helping reduce the risk of unsuitable materials entering mass production.


PE-Coated-Paper Manufacturing & Supply Network
Casperg Paper has a full set of production equipment for laminating, slitting, rewinding and cutting in its own factory, which can complete laminating composite and post-processing in an integrated manner. The maximum master roll width of products can reach 2850 mm. The finished roll diameter is controllable. The base paper grammage ranges from 80 to 350 g/㎡, and the PE coating grammage is 8–40 g/㎡. Both single-sided and double-sided PE extrusion coating can be customized. β-ray on-line monitoring together with laboratory extraction gravimetric method is adopted to test the PE coating grammage. The annual production capacity of coated paper is approximately 50,000 tons. Conventional orders can be delivered within 7–12 days, while customized specifications take 15–25 days. The products hold ISO system certification and FSC certification, meeting global foreign trade packaging requirements.

Frequently Asked Questions About PE-Coated-Paper
1. What is PE-coated paper used for in food packaging?
PE-coated paper is paper or paperboard with a polyethylene layer extrusion-coated onto one or both sides. It is commonly converted into paper cups, paper bowls, takeaway containers, ice cream cups, cup-bottom rolls and selected food wrappers. The required base paper and coating structure depend on the food type, contact temperature, storage conditions and converting process.
2. What is the difference between single-side and double-side PE-coated paper?
Single-side PE-coated paper has a polyethylene layer on one side and is commonly used where the food-contact surface requires moisture resistance and heat sealing. Double-side PE-coated paper has PE on both sides and is often selected for cold-drink cups, ice cream packaging and applications exposed to exterior condensation. The final structure should be confirmed according to the finished package and forming equipment.
3. How do I choose the correct grammage for PE-coated cupstock paper?
The correct grammage depends on cup or container size, required stiffness, forming speed and end use. Larger cups and food containers normally require a stronger base paper, but increasing grammage unnecessarily also increases material cost. Send us the finished-product dimensions, capacity, forming-machine information and current material specification so we can recommend suitable PE-coated cupstock paper.
4. Are base-paper grammage and PE coating weight quoted separately?
Yes. A professional PE-coated paper specification should state the base-paper grammage and PE coating weight separately. For example, the quotation should distinguish the weight of the paper substrate from the polyethylene applied to each side. This allows buyers to compare offers accurately and avoid receiving a lower base-paper or coating weight than expected.
5. Can PE-coated paper be used for both hot and cold food packaging?
Yes, but one specification should not automatically be used for every application. PE-coated paper for hot-drink cups, cold-drink cups, soup bowls, ice cream cups and takeaway boxes may require different base-paper stiffness, coating sides and heat-sealing performance. Buyers should provide the food type, filling temperature and expected storage conditions before confirming the material structure.
6. Do you supply PE-coated paper rolls and sheets?
PE-coated paper can be supplied as jumbo rolls, machine-ready slit rolls, cup-bottom rolls or customized sheets. The most suitable format depends on whether the buyer performs printing, slitting, die-cutting or container forming in-house. Roll and sheet dimensions should be confirmed before production to match the buyer's converting workflow.
7. Can you customize the roll width, diameter and core size?
Yes, custom-width PE-coated paper rolls can be produced according to the buyer's equipment requirements, subject to manufacturing limits. Please provide the required roll width, maximum roll diameter, core diameter, winding direction and acceptable joint quantity. Confirming these details helps reduce trimming waste, loading problems and machine downtime.
8. Will your PE-coated paper run on my cup-forming or container-forming machine?
Machine compatibility depends on paper stiffness, thickness, coating weight, surface treatment, roll tension and heat-sealing conditions. Before ordering PE-coated paper rolls for paper cup manufacturing, buyers should provide the machine model, production speed, heating or ultrasonic sealing method and existing material specification. Trial material is recommended when introducing a new paper structure.
9. Is the surface suitable for custom printing?
Printable PE-coated paper can be supplied with the appropriate surface and corona-treatment requirements, subject to confirmation. Buyers should specify the printing method, ink system, number of colors and whether printing will be completed before or after coating. Custom printed PE-coated paper rolls or sheets also require artwork approval and color-tolerance confirmation before mass production.
10. Can I request samples before placing a bulk order?
Existing samples may be available for basic material evaluation, while specification-matched trial material depends on the paper grade, coating structure and dimensions required. Buyers should test stiffness, printability, die-cutting, heat sealing and machine runnability before approving a bulk PE-coated paper order, especially when changing suppliers or material structures.
