REACH
SVHC statement for the quoted grade, if requested.
polyethylene sheet
Polyethylene Sheet Sourcing is an independent sourcing partner for US buyers. We do not extrude plate, hold a warehouse or publish a price list. Share thickness, width, quantity and destination so factories can answer the same polyethylene sheet line.
What a polyethylene sheet request has to decide before anyone talks about money
Neighbouring names in this family are not interchangeable SKUs. A factory that fills a blank axis will pick its own catalogue default. The matrix below is a checklist of questions. It is not a published rating for any option on this site.
| Axis | Thermal | Chemical | Mechanical | Compliance |
|---|---|---|---|---|
| Buyer writes | Service temperature in °F or °C and the medium | Whether the sheet sees water, oil, food or outdoor UV | Thickness in inches or millimetres; tensile or abrasion if the drawing cites them | Named ASTM method, FDA 21 CFR 177, REACH SVHC or none |
| Factory confirms | Grade claim for that temperature window | Whether the quoted resin is LDPE, HDPE or UHMW for that duty | Density in g/cc if used to distinguish grade; sheet size | The current document for the quoted item, not a plant brochure |
| Stays buyer-owned | Whether outdoor UV stabilizer is required | Food-contact or drinking-water files, if any | Cut-to-size versus a stocked blank | Which certificate travels with the lot |
Grouped request fields for polyethylene sheet
Leave an axis blank and two factories will not be quoting the same good. Shore A belongs on elastomers, not on this family. Working pressure in psi belongs on hose, not on plate.
Geometry
| Thickness | Inches or millimetres. Do not write “standard” or “6 mil” unless that is the actual film gauge you want. |
|---|---|
| Width and sheet size | Finished blank or a cut from a larger plate. 4×8 is one possible blank, not a synonym for the family. |
Grade identity
| Density | g/cc or g/cm³ if the buyer uses density to separate LDPE from HDPE. Example ranges from public polymer tables are about 0.91–0.93 (LDPE) and about 0.94 (HDPE); the quoted lot still has to confirm its own figure. |
|---|---|
| Color / finish | Natural, black or a named color; UV package if outdoor. |
Procurement
| Quantity | Sheets by thickness, not a lump count across gauges. |
|---|---|
| Documents | Dimensional page, material declaration, or a named ASTM method. A company ISO 9001 page is not a substitute. |
What this desk actually does with a polyethylene sheet brief
-
1. Name the form
Point at a reviewed inquiry option — standard-size, cut-to-size, color, UV-stabilized or thicker gauge — without treating the label as stock.
-
2. Keep units visible
Thickness stays in inches or millimetres. Density, if used, stays in g/cc. We do not convert a mil film request into a plate quote without writing the change down.
-
3. Issue the same list twice
The same axes go to more than one factory so replies can sit side by side on packing, Incoterms and documents.
-
4. Read the offer against the request
A cheaper-looking number on a different Incoterm is a different deal. We do not recast it as a percentage saving.
Files belong to a quoted line, not to this desk
REACH, RoHS, FDA 21 CFR 177, ISO 9001, IATF 16949 and UL 94 names below are document types a buyer may ask a factory to attach. They are not badges Polyethylene Sheet Sourcing issues, and a plant certificate does not replace a lot test.
RoHS
Restriction declaration tied to the quoted item.
FDA 21 CFR 177
Food-contact file only when the buyer asked for that duty.
ISO 9001
Plant system page. Not a dimensional report.
IATF 16949
Automotive quality system, if the receiving plant requires it.
UL 94
Flame rating only when the drawing cites a specimen thickness.
Where buyers usually take a polyethylene sheet request
OEM fabrication
Guards, liners and cut pads. Thickness and blank size stay on the drawing.
Tank and wear work
HDPE-class density and chemical notes are buyer decisions, not a promised life.
Packaging film vs plate
A mil-gauge film line is not a thick plate. Write the unit before the factory guesses.
Outdoor covers
UV stabilizer / HALS is a request field. Weathering hours are not published here.
Procurement situations, not customer reviews
These cards are worked examples. They are not testimonials, named buyers or claimed savings.
Plant liner replacement
A maintenance buyer has a black plate thickness on a worn liner and no grade name. The request asks the factory to state density in g/cc, sheet size and the ASTM method used for tensile strength (MPa / psi) if they print one.
Cut-to-size trial
A fabricator needs one sample panel before a repeating SKU. Sample and production stay on separate lines so setup is not hidden inside a unit price.
Food-contact question
A packaging engineer asks whether a natural sheet can carry an FDA 21 CFR 177 file. The file has to name the grade and lot. This desk does not certify food contact.
Send a polyethylene sheet brief we can issue more than once
Include thickness, sheet size, quantity, destination and the documents you need. Optional budget and supplier preference can sit in the same requirement field. No existing quotation is required.
