If you’ve ever chased a wobbling load down a warehouse aisle (I have, more than once), you already know the humble hand pallet wrap is doing more heavy lifting than it gets credit for. LIYA’s “Manual Stretch Film/pe Stretch Film/pallet Wrapper/winding Film/strong Stretch Packaging Film/logistic Tray” is built in Plastic Packing Park, Xiongxian, Baoding, Hebei, China 071800—an area that quietly turns out a lot of the film used by 3PLs and food distributors you’ve definitely heard of.
Material: LLDPE with metallocene for toughness and cling. Process: primarily cast extrusion for high clarity and consistent gauge. The result—high tensile strength, strong retraction force, puncture resistance, and transparency. In fact, many customers say the “grab” feels secure without over-tacking adjacent pallets.
| Parameter | Typical Value (≈) | Test Standard |
|---|---|---|
| Thickness | 12–30 μm (common: 15/17/20 μm) | Micrometer sampling per ISO 4593 |
| Tensile strength | 28–38 MPa MD; 18–28 MPa TD | ASTM D882 |
| Elongation at break | 350–500% | ASTM D882 |
| Puncture (dart) | 600–1000 g | ASTM D1709 |
| Clarity/Haze | Low haze; high clarity | ASTM D1003 |
Service life: around 12 months stored cool and dry (UV options available; outdoor performance may vary).
Resin selection → Cast extrusion with multilayer die → Edge trim & gauge control → Slitting to width (300–500 mm) → Core loading (1–3") → Cling side marking → Sampling tests (tensile, elongation, dart, haze) → Palletized pack → Final inspection to ISO 9001.
Certifications: typically ISO 9001/14001, RoHS/REACH compliance statements upon request. Load testing referenced against EUMOS 40509 (for transport stability).
| Vendor | Origin | Stretch (≈) | Puncture | Certs | Lead Time |
|---|---|---|---|---|---|
| LIYA | Hebei, China | 250–300% | High | ISO 9001/14001, REACH | 10–20 days |
| Generic A | SEA | 220–260% | Medium | ISO 9001 | 20–30 days |
| Private Label B | EU | 240–280% | High | ISO 9001, EUMOS | 7–14 days |
Widths: 300–500 mm; thickness: 12–35 μm; colors: clear, black, blue tint; cores: 1–3"; private label; pre‑stretched rolls; low‑noise unwind. For high-humidity lanes, specify higher cling or printed “THIS SIDE OUT.”
Feedback is a bit anecdotal, sure, but the pattern is consistent: strong puncture resistance plus predictable stretch saves both film and headaches.
