Pe coated paper for sugar packing

When sourcing PE coated paper, you must focus on the Base Paper Weight (GSM) and the PE Coating Thickness. For sugar sachets, a common configuration is 40-60 GSM base paper with a 10-15 GSM PE layer. Ensure the paper has high tensile strength to prevent bursting during high-speed automated packing and excellent heat-sealing properties to ensure a moisture-proof barrier.

Since the paper is in direct contact with food, it must comply with FDA (U.S. Food and Drug Administration) or EU 10/2011 regulations. Look for suppliers who provide SGS or Intertek test reports confirming the absence of harmful plasticizers and heavy metals. Additionally, ensure the supplier holds an ISO 22000 or HACCP certification for food safety management systems.

The PE coating acts as a moisture and grease barrier, which is critical for sugar to prevent caking and clumping. For the exterior, ensure the paper is corona treated to improve ink adhesion for Flexo or Offset printing. High-quality PE coating ensures the sealing strength remains consistent, extending the product's shelf life in humid environments.

While standard PE is not biodegradable, many B2B buyers are shifting towards PLA (Polylactic Acid) coatings or water-based barrier coatings for eco-friendly branding. If sustainability is a priority, verify if the base paper is FSC (Forest Stewardship Council) certified, ensuring it originates from responsibly managed forests.

Always request a pre-shipment sample from the specific production batch. Utilize third-party inspection services (like V-Trust or QIMA) to verify the GSM accuracy, coating uniformity, and odor levels before the balance payment is made. On Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site factory verifications.

Prices for PE coated paper are heavily influenced by global pulp and resin indices. Negotiate based on Total Volume rather than a single order to secure 'VIP' pricing. For startups, look for suppliers willing to offer a lower MOQ (e.g., 500kg - 1 ton) for trial runs, but be prepared for a 5-10% price premium compared to full container loads.

PE coated paper is sensitive to extreme heat and humidity. Ensure the supplier uses heavy-duty moisture-proof wrapping and palletizes the rolls with edge protectors to prevent deformation. Specify FOB or CIF terms clearly in the contract, and ensure the container is inspected for leaks or holes before loading to avoid sea salt contamination.

Use Secured Trading Services provided by Made-in-China.com to protect your payment. Never transfer funds to personal bank accounts; always ensure the beneficiary name matches the company name on the business license. Retain a detailed Proforma Invoice (PI) that specifies the exact technical parameters (GSM, PE thickness, width) to serve as legal evidence in case of disputes.
