Product Description
The PE Tube Liner — also known as a lay-flat liner — is the most widely used inner liner for FIBC bags worldwide. Constructed as a simple continuous cylinder of polyethylene film, open at the top and typically heat-sealed at the base, this liner provides an effective and economical barrier against moisture, dust, and contamination for a vast range of bulk materials.
Manufactured from virgin LDPE or LLDPE resin, our PE tube liners are produced to match your exact FIBC bag dimensions, ensuring a precise fit that minimises wasted material and maximises usable capacity. Whether you need liners for a single trial shipment or a long-term automated filling line, our production capacity supports orders from 1,000 to over 100,000 units.

Frequently Asked Questions
Q1: What is the difference between a PE tube liner and a form-fit liner?
A PE tube liner is a simple cylindrical sleeve that the user manually positions inside the bag — it does not pre-conform to the bag’s internal shape. A form-fit liner is manufactured to match the exact internal geometry of the FIBC, including the fill spout and discharge spout, providing smoother filling and more complete discharge with less product residue. Tube liners are more economical; form-fit liners offer superior performance for high-value or flow-critical products.
Q2: What thickness of PE tube liner do I need?
For general dry bulk materials, 50–100 micron (3.2–4 mil) is standard. And for premium moisture-critical applications, combine a 100+ micron liner with our PE/AL liners. Share your product details, and we will recommend the correct gauge.
Q3: Can the liner be fitted into the bag at your factory, or do I fit it myself?
Both options are available. We can factory-fit liners into your FIBC bags before shipment (tabbed, glued, or loosely inserted as specified), or supply liners separately for you to insert at your own filling facility. Factory-fitting reduces handling steps and ensures consistent liner positioning.
Q4: What is the minimum order quantity for PE tube liners?
Standard MOQ is 5,000 pieces per specification. For trial orders to test fit and performance, we can accommodate 500–1,000 pieces at standard unit pricing. Contact our sales team for sample requests.
