Pallet shipping failure rarely announces itself in advance. A load that looked stable at the dock shifts in transit, cases topple, product is damaged, and a chargeback follows. The root cause, more often than not, isn’t the carrier, it’s the film. 

Stretch film is the primary variable in load containment, and choosing the right film for the load profile is a technical decision, not just a purchasing one. This guide covers the fundamentals of load containment strategy, the critical differences between film types, and how IPG’s stretch film portfolio maps to real-world shipping requirements, including the specific demands of food processing and high-barrier applications.

**WHY IT MATTERS** 

What Load Containment Actually Means

Load containment is the measurable force holding a pallet together in transit. It’s determined by three interacting variables: the film’s stretch percentage, the number of wraps applied, and the film’s resistance to elongation under sustained tension. Getting any one of these wrong, under-stretching, over-stretching, or using a film with insufficient puncture resistance for the load type, produces a failure.

| **THE TWO FAILURE MODES TO DESIGN AGAINST** 1. Under-containment: insufficient tension allows load movement during transit — product shifts, cases lean, and damage occurs on arrival. 2. Over-wrapping with under-specified film: excessive layers of the wrong film cost more, add weight, and still fail under sharp corners or heavy loads because the film’s mechanical properties are mismatched to the application. |

The goal of a load containment strategy is to specify the minimum film needed to maintain a stable load through the entire shipping cycle, from wrap station to unload, for a given load weight, shape, and transit distance. That means matching film type to load profile before optimizing for cost.

**MATERIAL SCIENCE**

Cast vs. Blown Film: What the Difference Means in Practice

IPG produces both cast and blown [stretch film](https://www.itape.com/products/stretch-film/). The manufacturing process determines the film’s mechanical properties, and the right choice depends on what you’re wrapping. 

| **CAST FILM** | **High clarity, quiet unwind, consistent gauge** Produced on cast extrusion lines, cast film offers excellent optical clarity, a quiet unwind that reduces packer fatigue on high-volume lines, and consistent gauge across the roll. It stretches smoothly and predictably, making it the standard choice for uniform, stable loads. IPG’s StretchFlex® hand wrap and Genesys® machine films are cast. |
| --- | --- |

| **BLOWN FILM** | **Superior puncture resistance, aggressive cling, higher memory** Blown film is biaxially oriented during manufacturing, giving it significantly better puncture resistance and higher elastic memory — meaning it maintains containment force more aggressively over time. The tradeoff is a louder unwind and less optical clarity. For irregular loads, sharp-edged cases, or heavy product that resists uniform wrapping, blown film outperforms cast. IPG’s StretchFlex® HWII and SF3 machine film are blown. |
| --- | --- |

| **PRE-STRETCHED FILM** | **Reduced physical effort, consistent tension, lower weight per pallet** Pre-stretched film is processed before it reaches the packer — eliminating the need for the operator to apply tension manually. This reduces physical strain on high-volume hand-wrap lines, produces consistent wrap tension regardless of operator technique, and reduces the weight of film applied per pallet. IPG’s Orbit Air™ B is designed specifically for this application profile. |

**FOOD SAFETY & HIGH-BARRIER APPLICATION** 

What food processing operations require from stretch film 

Food processing and distribution environments impose requirements beyond standard load containment. The film must perform under cold chain conditions, comply with food-contact safety requirements, maintain integrity through condensation cycles, and — increasingly — meet sustainability commitments without sacrificing performance.

| **KEY REQUIREMENTS FOR FOOD& HIGH-BARRIER STRETCH FILM**  Food-contact safety: film must be manufactured from food-safe resins with no plasticizer migration risk. Cold chain performance: cling and containment must hold at refrigerated and frozen temperatures where standard films lose elasticity. Moisture resistance: the film must not degrade or lose adhesion when condensation forms on the load surface. Sustainability compliance: many food retailers and processors require recycled content or recyclable packaging materials. |
| --- |

IPG’s [StretchFLEX® PCR hand film](https://www.itape.com/product/stretchflex-pcr/) addresses the sustainability dimension directly. With 60% total recycled content, 30% post-consumer recycled (PCR) and 30% post-industrial recycled (PIR) it carries Cradle-to-Cradle certification and is suitable for food processing applications. It maintains the load security and puncture resistance expected from a hand film, while contributing to circularity goals without requiring a separate SKU or specialized equipment.

For machine-applied applications in food environments, IPG’s cast machine films — including the Genesys® line — are produced with food-safe resin formulations and are suitable for use in temperature-controlled distribution. High clarity allows barcode scanning through the film without unwrapping, a practical requirement for high-throughput food distribution centers.

**CHOOSING THE RIGHT SOLUTION** 

Load Profile to Film Recommendation 

The fastest path to the right film specification is matching film properties to load characteristics. Use the guide below as a starting framework, then validate with your volume and equipment before finalizing.

| **LOAD PROFILE** | **HAND WRAP RECOMMENDATION** | **MACHINE FILM RECOMMENDATION** |
| --- | --- | --- |
| Stable, uniform boxes | Standard cast hand wrap (HWI) | Standard cast machine film (Genesys®) |
| Heavy or dense loads | StretchFlex® blown wrap (HWII) | Genesys® Ultra high-performance machine film |
| Irregular / sharp corners | StretchFlex® blown wrap (HWII) | StretchFlex® SF3 blown machine film |
| Food processing / FDA | StretchFLEX® PCR (food-grade safe) | Genesys® cast machine film (food-safe) |
| High-volume; cost reduction | Orbit Air™ B pre-stretch | G7 ultra-thin machine film |
| Sustainability goals | StretchFLEX® PCR (60% recycled) | G7 or StretchFlex® PCR machine options |

**APPLICATION STRATEGY** 

Five Wrapping Principles that Determine Containment Performance 

| **01** | **Always anchor to the pallet first** The bottom wrap must grip the pallet itself, not just the bottom layer of cases. Two to three revolutions at pallet level, pulled tight with slight downward tension, establishes the foundation. A load that isn’t anchored at the base will slide regardless of how well the upper layers are wrapped. |
| --- | --- |

| **02** | **Apply consistent tension throughout** Tension should be firm and consistent from bottom to top. Slack wraps in the middle of a load create a hinge point where the pallet will flex and eventually fail. With pre-stretch film, the tension is built in. With standard hand wrap, technique matters, and higher-output operations should consider a dispenser or pre-stretch film to remove the variable. |
| --- | --- |

| **03** | **Overlap wraps by 50% minimum** Each revolution should overlap the previous wrap by at least 50%. Less than that creates weak bands between wraps where the load can separate. For heavy or unstable loads, increase to 75% overlap on the critical middle section. |
| --- | --- |

| **04** | **Add corner passes on irregular loads** If the load has corners or edges that protrude, add diagonal passes across those stress points after completing the standard spiral wrap. This distributes film over the sharp edge rather than relying on a single layer to resist puncture. |
| --- | --- |

| **05** | **Top-tie to the load, not just to itself** The final top wraps should cross the top surface of the load and tie down to the sides — not simply circle the top tier of cases. A film cap that doesn’t actually engage the top layer of the product provides almost no resistance to top-case displacement in transit. |
| --- | --- |

**BOTTOM LINE** 

Film Specification is a Load Containment Decision

The right stretch film for a pallet shipping operation isn’t the cheapest available per roll — it’s the film that delivers the required containment force for the load type, in the operating environment, at the lowest total cost per pallet. For food processing operations, that calculation also includes food-contact compliance, cold-chain performance, and sustainability requirements.

IPG’s stretch film portfolio — spanning hand wrap, machine film, blown and cast constructions, pre-stretch formats, and recycled-content options — covers the  
full range of those requirements. The right specification starts with the load profile.
