Ultra-Thin Pre-Stretched LLDPE Film | Folded-Edge Pallet Wrap

Engineered by mechanically elongating 100 percent virgin mLLDPE cast film during secondary slitting and rewinding, this pre-stretched film reduces material consumption per pallet by up to 50 percent. Featuring dual-folded reinforced edges, it operates at gauges between 6 micron and 10 micron without suffering edge tears during manual or semi-automatic wrapping. By pre-expanding the film near its ultimate yield point during manufacturing, operators can wrap pallets at full walk speed while maintaining load retention.

Film Structure & Material

The pre-stretching process realigns polymer chains longitudinally, converting raw elasticity into continuous tensile yield strength.

Film Processing & Layer Setup:

Layer A (Inside): Controlled High-Cling Layer - Tackifier Formulation
Layer B: Structural Core Layer - Metallocene LLDPE (mLLDPE) Polymer
Layer C: High-Tensile Orientation Layer - C8 Octene Copolymer
Layer D: Structural Core Layer - Metallocene LLDPE (mLLDPE) Polymer
Layer E (Outside): Non-Cling / Low-Friction Layer - Slip-Engineered LLDPE

Edge Reinforcement Mechanism:

Double-Folded Edges: Folded margins create a 2-ply reinforced boundary on both sides of the web. This prevents micro-notches caused by roll edge impacts from propagating into full-width snaps during application.

Molecular Orientation: Pre-orienting the film during production eliminates neck-down width reduction, ensuring full-width pallet coverage with fewer wrapping turns.

Zero Recycled Resin Content: Formulated without recycled post-industrial scrap to maintain consistent film thickness and eliminate gel inclusions.

Application & Load Compatibility Guide

Light / Crushable Cargo (Tissue, Corrugated Boxes, Empty Containers):

6 micron to 7 micron Film. Prevents box crushing or corner deformation caused by traditional film contraction force.

Standard Palletized Freight (Uniform Stacked Goods up to 600 kg):

7 micron to 8 micron Film with Folded Edges. Provides stable load containment at minimal film weight.

Cold Storage & Refrigerated Warehouses (0 to -25 Degrees Celsius):

Cold-Resistant Formulation. Retains flexibility and cling force in freezing temperatures where standard film turns brittle.

High-Speed Manual Wrapping Stations:

Extended core or light-core rolls (1.5 kg total weight) reduce operator wrist fatigue over multi-shift operations.

Performance Benefits

30 to 50 Percent Material Reduction:

Wraps the same pallet volume using half the total polymer mass compared to 17 micron or 20 micron standard films.

Ergonomic Manual Application:

Operators walk forward without pulling or leaning back under high tension, improving workplace ergonomics and wrapping speed.

Pre Stretched Hand Stretch Film suppliers

Zero Neck-Down Coverage:

Film retains its full nominal width (e.g., 450 mm) during application, reducing the required overlapping passes per pallet.

Impact-Resistant Roll Margins:

Folded edges allow rolls to survive accidental drop impacts onto warehouse floors without ruining the roll end-face.

Standard vs Pre-Stretched Film Comparison

Material Usage per Pallet:

Standard 20 micron film uses approx. 250 g to 350 g per pallet. Pre-stretched 7 micron film uses approx. 120 g to 160 g per pallet.

Physical Effort Required:

Standard film requires up to 15 kg of manual pulling force to achieve stretch. Pre-stretched film requires under 2 kg of tension to apply.

Roll Length and Yield:

A standard 3 kg hand roll yields approx. 200 m to 300 m of film. A pre-stretched 3 kg roll yields 600 m to 800 m of usable film.

Waste Management Impact:

Cuts post-use packaging plastic waste weight by up to 50 percent, helping industrial facilities meet corporate ESG plastic reduction targets.

Quality Control Protocols:
Dynamic Tension Calibration: Rewinding lines utilize closed-loop load cells to maintain consistent tension, preventing roll telescoping or tight-core crushing.

Edge Width Inspection: Optical sensors measure folded edge width continuously to ensure a uniform 3 mm to 5 mm double-ply edge profile.

Micron Thickness Verification: Ultrasonic gauges verify primary film gauge (+/- 3 percent tolerance) prior to mechanical pre-stretching.

Scale-Integrated Weight Verification: Every carton undergoes automated line weighing to guarantee net film length and net plastic weight accuracy within +/- 1 percent.

FAQ

Q: How does a 7 micron pre-stretched film maintain load containment equivalent to a 17 micron standard film?

A: Standard film stretches while being applied, which reduces its thickness on the pallet unevenly. Pre-stretched film is pre-elongated under controlled factory temperatures near its yield point, orienting its polymer chains. Combined with double-folded edges, the film acts like a rigid band with high tensile resistance, holding cargo securely without stretching further during transit.

Q: What prevents ultra-thin pre-stretched film from tearing when hitting sharp pallet corners?

A: Puncture resistance is maintained through two structural features: first, the middle film layers contain high-density Metallocene LLDPE (mLLDPE) resins; second, double-folded edges reinforce both outer boundaries. If a sharp edge contacts the center of the film, the reinforced double-ply edges absorb the tension and prevent the tear from splitting across the entire roll width.

Q: How much material cost savings can a warehouse expect when switching to pre-stretched film?

A: Facilities transitioning from standard 17–20 micron hand film typically achieve a 30 percent to 50 percent reduction in total plastic weight consumed per wrapped pallet. Because pre-stretched rolls contain up to twice the linear meters per kilogram compared to standard film, freight costs per meter of film and storage footprint are also significantly reduced.

Q: Can pre-stretched film be used on standard semi-automatic turntable wrapping machines?

A: Yes. Machine-grade pre-stretched film (typically 8 micron to 10 micron) is designed for machine carriages without powered pre-stretch systems or machines set to low stretch ratios. It delivers pre-stretched benefits to simple friction-brake machines without requiring expensive carriage hardware upgrades.

Q: What options are available to eliminate paper core waste for environmentally focused buyers?

A: We manufacture coreless pre-stretched film rolls. These rolls are wound around a removable mandrel during production and used with reusable plastic hand grips. Coreless formats eliminate 100 percent of paper core weight, reducing shipping weight and eliminating core disposal costs for the end user.

Q: What quality documentation is provided to verify net film length and gauge tolerances?

A: Every shipped order includes a Factory Inspection Certificate of Analysis (COA) confirming primary gauge tolerance (+/- 3 percent), edge fold integrity, ultimate tensile strength (ASTM D882), and net film weight per roll. Batch retention samples are kept for 12 months to ensure complete quality traceability.
