How Do You Specify a PE Flat Bag?
Short answer: Choose a PE flat bag when an open-top lay-flat construction fits the packing process; specify usable dimensions, thickness basis, material, printing and packing before quoting.
Scope: This page covers open-top PE film flat bags. Other bag constructions are outside this product page.
Before finalizing this construction, compare it with the other PE formats in the View our two PE products; then return to this page to confirm the product-specific fields.
For a step-by-step view of how specification, film formation, conversion, inspection and packing relate, see the PE flat bag and film roll stock manufacturing process guide; the actual route remains specification-dependent.
PE flat bags are open-top bags without an integrated closure; confirm whether that opening fits the packing workflow before requesting a written review.

PE Flat Bags, Made to Your Specifications
Flat bags are open-top polyethylene bags without an integrated closure. They can be specified for retail packing, component separation, protective covering and other uses. LDPE, HDPE, LLDPE or a PE blend can be reviewed against the required clarity, stiffness, toughness, sealing and regulatory context.
| Specification | Review basis |
|---|---|
| Material review | PE resin or blend selected against the intended use and written performance requirements |
| Dimensions & thickness | Buyer-specified dimensions and thickness basis; capability and tolerances confirmed in writing |
| Bag Type | Open-top, lay-flat bags (no closure) |
| Printing review | Artwork, color count, print area and acceptance criteria reviewed from the final files |
| Order quantity | Planning baseline: 10,000 pieces per specification; a trial quantity from 5,000 pieces may be evaluated. Final quantity is confirmed after the full size, thickness, material, printing and packing specification and current production plan are reviewed. |
| Written quotation | Price, trade term, schedule and validity are issued only after specification review |
Common Applications
Retail & Apparel
Open-top bags can be specified for garments, linens, soft goods and retail merchandise.
Industrial Covering
Size, thickness and handling requirements should be matched to the item and storage conditions.
Food-Related Projects
State the food-contact scenario and destination market in the RFQ. Material and document suitability must be reviewed and accepted in writing for the specific project.
Quote Checklist
Send a complete specification so manufacturability, commercial terms and the response schedule can be reviewed before a written quotation is issued.
Not sure which size or thickness to specify? See our PE flat bag and film roll stock size guide, material guide, thickness guide and two-product catalogue before sending your requirements. If microns, millimetres or per-wall versus total thickness are unfamiliar, start with the PE flat bag and film roll stock thickness basics guide. For an initial material side-by-side review, use the PE material comparison tool; for a quick unit check, use the PE flat bag and film roll stock thickness converter. If the bag will be printed, read the PE flat bag and film roll stock printing methods guide before finalizing artwork. Before approving a sample or shipment, use the PE flat bag and film roll stock quality inspection guide to organise the checks agreed for the project.
1. Use, Size & Thickness
Intended contents, width × length, thickness value and whether it is single-wall or total thickness.
2. Quantity, Printing & Packing
Quantity per specification, artwork and color count, packing method and acceptance criteria.
3. Destination & Trade Term
Destination country or port, requested Incoterm and any market-specific document requirements.
PE Flat Bag Questions
How Do You Specify a PE Flat Bag?
Choose a PE flat bag when an open-top polyethylene construction fits the packing process. Final construction, dimensions, thickness and packing requirements are confirmed for each project.
Can You Make Custom PE Flat Bags?
Custom PE flat bags can be reviewed from the finished dimensions, thickness basis, material, quantity, printing and packing. A written quotation confirms the production and delivery assumptions for the specified bag.
Can PE Flat Bags Be Clear or Natural?
Clear or natural appearance can be reviewed as a requested PE film property. Confirm the resin, grade, construction, thickness and final appearance against the packed product and an accepted sample before production.
What is the MOQ for PE flat bags?
A standard planning baseline is 10,000 pieces per specification, and a trial quantity from 5,000 pieces may be evaluated. The final MOQ is confirmed after reviewing dimensions, thickness, material, printing, packing and the current production plan.
How should PE flat bag thickness be specified?
State whether thickness is per wall or total, include the preferred unit and tolerance, and describe the product and handling conditions. A representative sample or agreed test may be used before production.
How are PE flat bag quotes prepared?
A written quote follows review of construction, finished dimensions, thickness, material, quantity, artwork, packing and delivery terms. The approved specification records the assumptions used for the quotation.
How are samples charged for a PE flat bag order?
Samples are charged at cost and confirmed against your specification before dispatch. The sample charge is credited against your first production order; courier charges are quoted separately.
Need a Sample Plan?
Sample availability, sample type, representativeness, charges, courier cost and timing are confirmed for each project before anything is dispatched.
