Cold Chain Packaging in Europe: Film & Strapping That Perform at Low Temperatures

Industry Data: Temperature-controlled supply chains lose a significant share of product to handling and packaging failures — collapsed or unstable pallets, condensation damage and seal failure — in addition to temperature excursions themselves. Source: Cold-chain logistics and food-loss studies.

Cold chain packaging has to do everything normal packaging does, then keep doing it at minus twenty. Standard stretch film can go brittle and lose cling in a freezer; strapping can slacken as loads contract; and every move between temperature zones invites condensation. Greenstrix (greenstrix.com) supplies high-elongation LLDPE film and strapping that perform across the cold chain — and this guide explains how to specify them.

1. Why Cold Defeats Ordinary Packaging

Polymers behave differently when cold. A stretch film that clings and stretches at room temperature can become stiff and lose tack near freezing, so wraps loosen and pallets destabilise. The film must be formulated and specified for low-temperature performance, not just chosen on room-temperature numbers.

Loads change too. As goods cool, they contract, and securing applied at ambient temperature can slacken. Combined with the vibration of transport and the condensation of zone changes, this is why ordinary packaging fails in the cold chain where it would pass at ambient.

2. Specifying Film for Frozen & Chilled

The key film property for cold chain is retained performance at temperature: cling, flexibility and puncture resistance that do not collapse when cold. High-elongation LLDPE handles this better than basic films, maintaining containment as the pallet moves through the chain. Application matters as much as material — wrapping to a defined containment force, with allowance for load contraction, keeps the pallet stable from the freezer to the chilled DC.

Greenstrix LLDPE film offers up to 300% elongation, maintaining containment force at low temperature for both manual and automated cold-store wrapping. It is suited to chilled and frozen pallet wrapping where standard film fails.

3. Condensation, Stability & Automated Cold Stores

Automated cold stores are unforgiving: a pallet that leans or sheds product is rejected by the system, stopping the flow. Tight wrapping to a proper containment force keeps the pallet square and stable through the freezer environment, which is essential for automated handling.

Condensation is the other cold-chain hazard. Each move between temperature zones can deposit moisture on the load; film that sheds this protects cartons, labels and product. Greenstrix LLDPE film provides both the stability and the moisture barrier the cold chain needs.

• Containment force — hold the pallet square for automated handling.
• Low-temperature cling — wraps stay put in the freezer.
• Moisture shedding — protects against zone-change condensation.
• Strapping — secures tall or heavy chilled loads against slackening.

4. Recyclability & Food-Sector Compliance

Food and pharma supply chains face strict packaging-waste and material rules under PPWR and national law, alongside retailer ESG commitments. Recyclable mono-material LLDPE film meets these without sacrificing cold-chain performance. Greenstrix supplies recyclable LLDPE film grades suited to chilled and frozen use, so cold-chain operators meet compliance and sustainability targets while keeping pallets stable and protected at temperature.

5. Frequently Asked Questions

Q: Does standard stretch film work in a freezer?

Often not well. Many standard films go brittle and lose cling at freezer temperatures, so wraps loosen and pallets destabilise. Cold chain needs high-elongation LLDPE film specified for low-temperature performance. Greenstrix supplies film suited to chilled and frozen use — contact sales@greenstrix.com.

Q: How do I stop cold chain pallets collapsing in automated stores?

Wrap to a defined containment force with low-temperature film and secure tall or heavy loads with strapping, allowing for load contraction as goods cool. A square, stable pallet is essential because automated cold stores reject leaning or shedding pallets. Greenstrix film supports this.

Q: What causes condensation damage in the cold chain?

Moving pallets between frozen, chilled and ambient zones causes warm moist air to condense on the cold load. Moisture-shedding film protects cartons, labels and product from this. Greenstrix LLDPE film provides both pallet stability and a moisture barrier.

Q: Is recyclable film available for cold chain use?

Yes. Greenstrix supplies recyclable mono-material LLDPE film grades that perform at low temperature, helping food and pharma cold chains meet PPWR, France's AGEC and retailer ESG requirements without losing securing performance.

Q: Does strapping slacken in the cold?

Securing applied at ambient temperature can slacken as the load cools and contracts. Using tension-retaining strapping and accounting for contraction at application keeps loads secure through the cold chain. Greenstrix supplies strapping suited to this alongside its film.
