Same-basis factory request
Turn a custom polyethylene plastic film manufacturer search into one written list several factories can answer. Plastic Film Sourcing issues that list. It does not manufacture polyethylene film, appoint a mill, or fill missing thickness on the buyer’s behalf.
Every custom polyethylene plastic film manufacturer quotation must state thickness in inches, mils or millimetres before two prices mean the same thing. We copy the buyer’s unit onto the request and ask both factories to restate that unit if one answers in mils and the other in μm.
Slitting, cores, export wrap, inland haul to the named US destination, and document sets are commonly left off a unit price. Those lines have to be asked for. This desk does not recast a cheaper Incoterm as a percentage saving.
Ask for the TDS that names melt flow index and density, plus any FDA 21 CFR 177 or REACH SVHC file the receiving plant wrote. A general “we can make PE film” capability claim is not evidence for the quoted width and gauge.
State whether a sample roll or sheet must be approved before the production lot. Sample width, gauge and document set belong on the request. This site does not publish MOQ or lead time.
Polymer family (LDPE / LLDPE / HDPE or a named blend), thickness in one unit, width and roll or sheet length, treatment, quantity by configuration, destination state or postal code, requested delivery window, and the documents that must travel with the lot. Optional budget and supplier preference can sit beside that list.
That remains the buyer’s decision. Blown film is often asked for toughness and orientation; cast film is often asked for gauge control and clarity. Factories may propose the other process. We write the substitution down instead of treating it as the same line. Extrusion and co-extrusion stay named if the buyer asked for layers.
One factory may quote 2 mil and another 50 μm. Those can be the same gauge after conversion, or they can be different. We ask both to print the same unit. Until they do, the quotes are not yet competitors.
“Need custom polyethylene plastic film manufacturer, standard roll, soon.” Factories fill gaps themselves: one assumes untreated LDPE, another a corona-treated LLDPE, a third a thicker HDPE liner. The numbers cannot be compared.
The same page names the inquiry option, polymer, thickness in mils, width, quantity, destination, packing and Incoterms. Two replies that answer that page can be laid side by side. A reply that answers three of the items is sent back.
Use the form. Drawings can follow after we reply. No existing quotation is required.
