HDPE Sheet - Durable, UV Resistant, Food Grade, Cut-to-Size


A field-tested look at modern polyethylene sheets

Spend enough time on shop floors and docks and you notice the quiet workhorses. One of them is the HDPE sheet—the panel fabricators grab when they need toughness without the drama. Actually, it’s been gaining traction for years in food plants, marine gear, playgrounds, even chemical tanks. What follows is a practical rundown, the kind I wish I’d had on my first procurement trip.

Quick look, with real-world specs

Origin: No.316 Pingan West Street, Shunping County, Baoding City, Hebei, China 072250. Surface is glossy; colors include natural, black, yellow, red, green—and, to be honest, almost anything customers ask for.

Property / Spec Typical value (≈) Method / Note
Thickness 3–20 mm Custom tolerances on request
Width 1000–1500 mm Standard rolls/plates
Length Any length Cut-to-size available
Density 0.95 ± 0.02 g/cm³ ASTM D792
Tensile @ yield ≥ 26 MPa ASTM D638
Elongation > 600% ASTM D638
Shore D ~69 ± 3 ASTM D2240
Vicat softening ~125 °C ASTM D1525
Water absorption ASTM D570
HDPE Sheet - Durable, UV Resistant, Food Grade, Cut-to-Size

Process flow (how it’s actually made)

  • Materials: 100% virgin HDPE resin (ASTM D4976 PE), optional UV stabilizer, food-contact grades on request.
  • Methods: Melt filtration → single-screw sheet extrusion → polished-roll calendering for glossy finish → cooling → trimming → stress-relief anneal (when tight flatness is needed).
  • Testing: Density (ASTM D792), tensile (D638), hardness (D2240), impact (D256), migration for food contact (FDA 21 CFR 177.1520), RoHS/REACH.
  • Service life: Around 10–20 years outdoors with UV package; temperature window ≈ -50 °C to +80 °C continuous (short excursions higher).
  • Industries: Food processing and cutting boards, marine fenders/dock bumpers, chemical tanks/liners, agriculture, playground panels, mining chute liners.

Why teams pick HDPE sheet

It machines cleanly, shrugs off moisture, and isn’t brittle in the cold. Many customers say sliding abrasion is where it shines; the coefficient of friction typically sits in the 0.2–0.3 range (dry), so parts don’t gall as quickly. And unlike metals, it won’t rust—obviously a win for fish farms and dairies.

Customization (what’s usually on the table)

Colors to match brand palettes, cut-to-size panels, CNC pre-drilling, textured faces, UV packages, and even anti-static grades. Lead times vary, but stocked colors in common thicknesses move fast; custom blends, a bit longer, which is fair.

Vendor snapshot (apples-to-apples-ish)

Vendor Resin / Grade MOQ Lead time Certifications Notes
Lida Plastic (Hebei) Virgin HDPE, food-grade options ≈ 500 kg 7–15 days ISO 9001, FDA compliance, RoHS Tight flatness, custom colors
Regional Distributor Mixed sources By sheet 2–5 days Varies Great for small rush jobs
Marketplace Seller Unspecified 1 sheet Unclear Claims only Verify test reports—seriously

Real-world snapshots

  • Marine pier fenders: HDPE sheet replaced timber; reduced maintenance 40% over 18 months (customer estimate).
  • Dairy cutting surfaces: food-grade HDPE sheet passed migration tests and cleaned faster, which staff loved.
  • Mining chute liners: thicker black HDPE sheet cut downtime by avoiding adhesive wear in wet slurry.

Compliance and testing (the fine print that matters)

Typical documentation: ASTM D4976 resin spec, tensile/density reports (D638/D792), FDA 21 CFR 177.1520 food-contact statement, RoHS/REACH declarations, and ISO 9001 quality management. Lab numbers vary by batch—real-world use may vary, as always.
