# PE-Coated Cupstock

PE-coated cupstock for cup converters sourcing from China. Specify the cup body or bottom, beverage, service temperature, coating sides and forming process. Our Chengdu team coordinates candidate factory grades and sample requirements around the finished cup and its destination.

[Discuss this specification](https://rbpaper.com/?source=%2Fproducts%2Fpaperboard%2Fpe-coated-cupstock%2F&product=paperboard&grade=PE-Coated+Cupstock#contact)

## Application & grade selection

- Paper cup bodies and bottoms subject to approved forming trials

- Hot or cold beverage cups with an appropriate agreed construction

- Cupstock purchases for a specified converter and end use

## Technical specification & TDS verification

Base board and finished coated stock are different specifications. Confirm both in a grade-specific TDS; no universal food-contact or recyclability claim is made.

| Parameter | Buyer requirement / factory evidence | Test / verification method |
| --- | --- | --- |
| Base board grammage | Base-board GSM and tolerance, separately from finished coated GSM. | ISO 536 or the agreed method; identify which material is tested. |
| PE coating | One or two coated sides, coating weight per side, surface/side identification and resin requirements. | Supplier coating specification and agreed verification method. |
| Caliper and stiffness | Finished caliper, machine/cross-direction stiffness and cup rigidity targets. | ISO 534; stiffness measured with the agreed method, including test geometry. |
| Sealing and forming | Cup machine/process, sealing method, coating side orientation and approved operating window. | Buyer forming trial, seal integrity and agreed leak test. |
| Liquid-contact conditions | Beverage/food type, contact duration, service temperature and required barrier performance. | Application-specific test plan and destination compliance requirements. |
| Moisture and surface | Moisture, print surface, odour/taste requirements and coating-defect limits. | ISO 287 where applicable; agreed sensory, visual and print checks. |
| Dimensions | Reel width/core/diameter or sheet/blank dimensions, grain direction and machine limits. | Agreed dimensional checks and forming trial. |

## Testing & document requirements

### Base board and coating specification

Request technical information for both the base board and the finished coated stock. Confirm base grammage, coating weight per side, finished caliper, resin information and identification of the food-contact and printing sides.

### Food-contact documentation

Provide the destination market, beverage or food type, contact duration and service temperature. Request declarations and relevant test reports that cover the exact board, coating construction and intended conditions of use, then review them with your importing and compliance team.

### Forming, sealing and leak trials

Share the cup machine, sealing method and intended operating conditions. Approve representative material through forming, seal-integrity and leak trials, with appearance and odour or taste requirements included where relevant.

### Fibre and environmental claims

If the order requires a certified-fibre, recycled-content or other environmental claim, state the exact claim and destination. Request supporting records for the proposed construction and confirm the wording that can accompany the supplied material.

## Packing & container planning

- PE-side identification and winding direction

- Reel width/core/diameter and weight limits

- Surface protection to prevent coating damage

- Moisture-resistant wrap and protected ends

- Batch identification for board/coating traceability

- Packing dimensions and verified container plan

| Planning field | Information to confirm |
| --- | --- |
| Shipment format | Reels, sheets or converted blanks; quantity by grade and net metric tonnes. |
| Reel handling | Width, maximum diameter, core inside diameter, maximum reel weight, winding direction and splice limits. |
| Sheet handling | Sheet dimensions, grain direction, sheets per stack, pallet dimensions, maximum stack height and pallet gross weight. |
| Protection and traceability | Moisture-resistant wrap, edge protection, end protection, pallet/packing specification, grade and batch labels. |
| Container plan | 20GP/40HQ option, actual package dimensions and gross weights, securing plan, equipment payload and destination handling/road limits; final net tonnes confirmed against the packing list. |
| Commercial basis | Named origin/destination, Incoterm, currency, quote validity, payment terms, required documents and target shipment window. |

Net cargo quantity is an order-specific result of dimensions, packing, actual weight and the relevant equipment and transport limits.

## Sample & approval workflow

- Submit the application, specification and any reference TDS.

- Review the proposed factory grade and document scope.

- Approve a representative sample against the agreed acceptance criteria.

- Confirm the quotation, inspection scope, packing and shipment terms in writing.

## Buying questions

Should I choose single-sided or double-sided PE?

The choice depends on your cup construction, beverage, service temperature and forming process. Provide these details so candidate grades can be evaluated; the coating option is confirmed by the factory.

Does 'food grade' or 'FDA' on a brochure prove suitability?

A general phrase is insufficient. Check the exact grade, coating, intended food-contact conditions and relevant reports or declarations for your destination.

Can you guarantee the cup will run on our machine?

A successful forming and sealing trial is needed. Share machine/process limits and approve the sample, seal integrity and leak results before the bulk order.

Can cupstock be supplied in reels or sheets?

Send the required format, dimensions, grain direction, coating side and quantity. Available options, minimum orders and packing are confirmed for the proposed factory grade.
