Adhesive Pack Tape Company is a manufacturer of vented stretch film for hot palletizing products that need airflow, heat release, moisture escape, and condensation control after wrapping. Made from perforated PE/LLDPE film, it helps hot-fill goods, agricultural products, fruits and vegetables, flowers, and ventilated pallet loads release trapped heat and vapour while keeping practical holding force.
Product Overview
Vented stretch film is made for pallet loads that still need to breathe after wrapping. Hot palletizing products, fresh produce, cut flowers, and moisture-sensitive agricultural goods may release heat, vapour, ripening gas, or surface humidity. When sealed with closed film, moisture can gather on cartons, cans, jars, labels, trays, and pallet corners, causing wet packaging, label lifting, rust marks, mould risk, or slower cooling.
This perforated stretch wrap uses a controlled hole pattern across the film web. The holes create airflow channels, while the remaining film bands provide cling, stretch recovery, and containment. For hot-fill beverages, sauces, canned food, pickles, bakery products, and pasteurized goods, it supports cooling after wrapping without leaving the load unsecured. For produce and flower transport, the breathable structure reduces sweating and keeps air moving through pallet sides.
Adhesive Pack Tape Company produces vented stretch wrap with holes for agri products in 400 mm, 450 mm, and 500 mm widths, with 2 inch or 3 inch paper cores. Common hole diameter is around 6-20 mm, and hole spacing is often 40-100 mm. These values are selected by temperature, pallet weight, cooling speed, open area, and stability needs.
Benefits
- Heat release: Warm air can leave hot-fill or freshly packed goods instead of staying trapped inside the pallet.
- Moisture escape: Vapour passes through holes, helping reduce wet cartons, damp labels, rusty cans, and surface moisture.
- Airflow for fresh goods: The film supports breathable wrapping for fruits and vegetables, flowers, plants, and agricultural products.
- Stronger film around holes: Reinforced film bands help reduce tearing during wrapping and corner contact.
- Balanced pallet stability: Holding force is kept around heavy ventilated pallets while breathing channels remain visible.
- Specification matching: Thickness, hole size, spacing, open area, width, length, and core size can match the wrapping method.
What Makes the Hole Pattern Important for Hot Palletizing Products?
The hole pattern affects both ventilation and strength. Airflow should remain open after the film is stretched, overlapped, and pressed against cartons or trays. In many wrapping conditions, 30%-50% overlap helps secure the load, but too much overlap can cover too many holes. If the open area is too small, warm vapour may still turn into condensation. If it is too large, the film may lose holding strength on tall or heavy pallets.

Applications
- Hot-fill beverages, canned food, sauces, pickles, jars, and bakery products that need heat release after wrapping
- Cold-room produce handling, where vented stretch films for wrapping fruits and vegetables help reduce sweating
- Flower, plant, and horticultural pallets, including vented stretch film for wrapping flowers with side ventilation
- Eggs, cereals, fodder, flour, and paper-based goods packed with breathable stretch film for agricultural products
- Chilled food, dairy products, frozen goods, meat, seafood, and other temperature-sensitive pallet loads
- Heavy ventilated pallets where vented stretch film for wrapping heavy pallets must provide airflow and holding force
How Can Airflow and Load Stability Be Balanced After Wrapping?
A ventilated pallet still needs to move safely through warehouses, cooling rooms, trucks, and export handling. The best result comes from matching open area to the load, not simply choosing the largest holes. Heavy ventilated pallets need stronger film bands around perforations, controlled stretch, and 2-3 secure base wraps. Operators should avoid wrapping so tightly, or overlapping so much, that every hole is covered. After wrapping, airflow channels should still be visible on the pallet sides.
FAQ
What is vented stretch film used for?
It is used when wrapped pallets must continue cooling or breathing after packing, such as hot-fill products, produce, flowers, chilled goods, and moisture-sensitive packaging.
How does perforated stretch wrap help control condensation?
The holes allow heat, vapour, and humidity to escape before moisture collects on cartons, labels, cans, or bottles.
Can vented stretch film hold heavy ventilated pallets?
Yes. Correct thickness, hole pattern, overlap, and film strength around perforations help maintain containment while keeping airflow open.
How should the hole pattern be selected?
Select it by product temperature, moisture release, pallet weight, cooling requirement, and wrapping overlap. Larger open areas improve airflow, while stronger film bands improve stability.
