manual pre stretched vented stretch film





As a manufacturer of manual pre stretched vented stretch film, Foshan Opalus Adhesive Products Co., Ltd. produces hand-applied pallet wrap for loads that need airflow, easier wrapping, and dependable pallet holding. The film is pre-stretched before winding and made with planned perforation lanes, so operators can wrap flower, fresh produce, dairy, refrigerated, and damp pallets with lower pulling force. Width, core style, hole layout, and wrapping performance should be confirmed through real pallet trials before repeat use.

Product Overview
Manual pre stretched vented stretch film is made for hand wrapping jobs where closed stretch film may trap heat or moisture inside the pallet. It is not simply ordinary hand film with holes added. Final performance depends on film thickness, pre-stretch level, roll width, hole lane design, and the film web strength left between perforations. If these details are not matched to the load, tearing may start at the hole edge, pallet corner, or crate contact point.
This product is commonly used for flower sleeves, ventilated vegetable crates, chilled dairy cartons, refrigerated beverages, and damp warehouse pallets. In these applications, the wrap needs to let air move through the load while still keeping cartons, crates, trays, or uneven pallet edges grouped during handling. When pallets move from cold storage to a warmer dock area, the wrapped load should be checked for visible condensation, carton softening at contact points, and whether the perforation lanes remain open after several wrap turns.
The pre-stretched structure helps operators wrap more consistently. Because the film has already been elongated before winding, workers use steady hand tension instead of pulling hard around every corner. During sample approval, check roll weight comfort, hole opening after wrapping, edge splitting near perforations, bottom wrap holding, and pallet stability after dwell time, pallet-jack movement, or forklift movement. Retained approved samples and batch identification help keep film feel, hole layout, and wrapping behavior consistent in repeat orders.

Benefits
- Lower pulling force helps operators wrap pallets more easily during repeated hand wrapping.
- Planned perforation lanes allow air movement around chilled, damp, or recently packed loads.
- Controlled film recovery supports pallet holding after the wrap is applied.
- 17 inch, 18 inch, 20 inch, and 500 mm widths fit common manual wrapping routines.
- 1000 ft, 1500 ft, and 3000 ft roll lengths can be matched to packing volume.
- 3 inch ID core and extended hand core options support different operator habits.
- Edge tear resistance can be checked around holes, crate corners, and pallet edges.
- Sample trials can confirm hole opening, condensation condition, load shift, and movement performance.

How Should the Vent Hole Pattern Be Matched With Manual Wrapping Tension?
The hole pattern should be chosen with film thickness, roll width, pre-stretch level, and the normal pulling force used by operators. Light flower carts or ventilated produce crates may work better with a more open layout because airflow is often more important than high containment. Dairy cartons, chilled beverages, or damp mixed pallets usually need more film web between holes to hold the load. During approval, wrap the pallet by hand at normal packing tension, then check whether holes stretch too far around corners, whether the edge splits, and whether the pallet stays stable after dwell time and movement.

Applications
- Flower and nursery pallets that need airflow around sleeves, trays, or cartons.
- Fresh fruit and vegetable crates that should not be sealed tightly with closed film.
- Dairy outer cartons moving through chilled storage and refrigerated transport.
- Refrigerated beverage pallets exposed to temperature changes during handling.
- Damp warehouse goods where trapped moisture should be reduced during holding.
- Farm, packhouse, cold storage, and distribution areas using manual pallet wrapping.
- Mixed loads requiring breathable pallet wrap with moderate containment.
- Seasonal or short-run packing lines where hand wrapping is more practical than machine wrapping.
What Should Be Confirmed Before Using Pre Stretched Vented Film for Cold-Chain or Damp Pallets?
Before repeat use, test the film on real cold-chain, flower, produce, dairy, or damp warehouse pallets instead of only using small carton samples. Confirm whether airflow paths remain open after several wrap layers, whether visible condensation is reduced during temperature transition, and whether cartons or trays stay secure without over-wrapping. The test should include bottom wraps, top coverage, corner contact points, edge tear resistance, roll handling comfort, load shift after dwell time, and pallet movement after wrapping. Vented holes support air circulation and moisture release, but they should not be described as preservation, anti-corrosion, or freshness certification.
FAQ
Is manual pre stretched vented stretch film suitable for all pallet loads?
No. It is mainly used for flower, produce, dairy, refrigerated, and damp pallet loads that need airflow. Dry, heavy, or sharp-edged industrial pallets may need closed hand film or a stronger stretch grade.
How is this film different from ordinary pre-stretched hand film?
Ordinary pre-stretched hand film usually has a closed structure. This product combines lower-force manual wrapping with planned perforations, so it supports airflow while still helping hold palletized loads.
Can the hole pattern be adjusted?
Yes. Hole lane layout, hole size, roll width, film thickness, and roll length can be adjusted according to pallet height, load weight, airflow requirement, and manual wrapping tension.
How should a sample be approved before bulk use?
Wrap real pallets by hand, then check hole opening, edge tearing, condensation after temperature change, load shift after dwell time, bottom wrap holding, and movement by forklift or pallet jack.
