What Is Stretch Film?

Stretch film is a flexible packaging film used to wrap and unitize products, cartons or bags on a pallet. When applied correctly, the film helps keep individual packages together and supports load stability during warehouse handling, storage and transportation.

Commercial stretch films are available in multiple constructions and performance grades. Film selection should therefore be based on the actual load and wrapping process rather than simply choosing the thickest available film.

Manufacturer product ranges show that stretch films can differ significantly in cling, puncture resistance, stretch capability, film gauge and machine compatibility.

1. Hand Stretch Film

Hand Stretch Film is designed for manual application.

An operator walks around the pallet while applying the film directly from the roll or through a compatible hand dispenser.

It is commonly suitable for:

Lower-volume pallet wrapping

Warehouses without automatic wrapping machines

Dispatch areas

Loads packed at multiple locations

Occasional or flexible wrapping requirements

Hand film provides operational flexibility because no fixed wrapping machine is required.

However, the final wrapping quality can depend significantly on operator technique, film tension and overlap.

For businesses wrapping only a limited number of pallets each day, hand film can therefore be a practical solution.

Berry Global, for example, describes conventional hand film for all-purpose manual warehouse wrapping while offering different widths, gauges and performance characteristics.

2. Machine Stretch Film

Machine Stretch Film is intended for automatic or semi-automatic pallet wrapping equipment.

Compared with manual wrapping, machine application can provide more repeatable film tension and wrapping patterns when the film, equipment and machine settings are correctly matched.

It is generally more suitable for:

Medium to high pallet volumes

Production lines

Distribution centres

Repetitive pallet sizes

Operations requiring consistent wrapping cycles

Machine films are available for different equipment types and pre-stretch requirements. Manufacturers specifically publish different machine-film grades depending on load type, puncture resistance, wrapping speed and machine capability.

This is why businesses should confirm their wrapper model and application conditions before selecting a machine film.

3. Pre-Stretched Film

Pre-Stretched Film has already been stretched during manufacturing before it reaches the operator.

This can make manual application easier because less force may be required from the user during wrapping.

Signode describes oriented/pre-stretched film as being pre-stretched during manufacture and designed to provide load containment with easier application. Berry similarly markets pre-stretched hand-film options designed to reduce application effort.

Pre-stretched film may be useful where:

Manual pallet wrapping is frequent

Operator effort is a concern

Consistent application is desirable

Material efficiency is being evaluated

4. Colored Stretch Film

Colored Stretch Film combines pallet wrapping with visual identification.

Depending on the film specification, colored or opaque films may be useful for:

Warehouse segregation

Load identification

Product concealment

Customer or route coding

Differentiating inventory categories

The exact opacity, color and film performance should always be confirmed from the supplied grade.

Which Stretch Film Should You Choose?

Before ordering, consider:

How many pallets are wrapped each day?

Is wrapping manual or machine-based?

What are the pallet dimensions?

Is the load regular or irregular?

Are there sharp corners or protrusions?

How heavy and stable is the load?

Will the pallet experience cold, humidity, dust or outdoor exposure?

What film width, core and roll format does the equipment support?

Different machine-film products are explicitly designed for different load classes and operating environments, which is why one film should not automatically be assumed suitable for every pallet.

Final Selection Advice

There is no single “best” stretch film for every application.

For lower-volume manual packaging, Hand Stretch Film may be suitable. Higher-volume operations may benefit from Machine Stretch Film, while Pre-Stretched Film can be useful where easier manual application is desired.

The final selection should be based on the actual pallet, wrapping process and required load containment.
