Industrial Pallet Wrap for Automated Packaging Lines: Film Performance Requirements

Automated pallet wrapping systems are essential for industries that prioritize consistency of packaging and throughput, be it manufacturing, logistics, food, beverage, export or any combination. However, for automatic wrapping lines, the combination of equipment is of lesser concern than the dependability and consistency of the Industrial Pallet Wrap in maintaining its mechanical properties with constant machine operation.

Automated packaging requires the stretch film to work with systems of controlled pre-stretch ratios and mechanical tension along with varying conditions of pallet loads. Films with inconsistent gauge, poor recovery force, or poor stability in elongation will consume more film, lead to a higher incidence of film breakage and Loss of wrapping system reliability.

As a stretch film manufacturer, Yalan Pack has developed Industrial Pallet Wrap solutions based on the characteristics of LLDPE and the application requirements, along with the use of multilayer films. Based on those properties, Yalan Pack offers blue stretch film solutions designed to maintain stable wrapping performance, load identification, and provide protection to the pallet.

Why Automated Packaging Requires High-Performance Industrial Pallet Wrap

Automated systems rely on fixed mechanical parameters (pre-stretch ratio, film tension, wrapping speed, number of wrapping cycles, and the containment force applied). Automated systems do not allow for variation in these parameters, whereas manual systems do. Therefore, Industrial Pallet Wrap should maintain consistent performance from the first to the last meter of the roll.

There are a number of packaging failures attributable to using stretch film that lacks appropriate stretchability. These failures include:

•   Film rupturing due to a high rate of operation

•   Variable wrapping tension between the different layers of a pallet

•   Impaired pallet stability during transit

In addition, stretch film with insufficient stretchability may create a less stable pallet by needing a greater quantity of material to achieve the necessary wrapping.

For industrial applications, there is a trade-off between strength, stretchability, and consumption of a stretch film. Strength of a stretch film typically increases with a marginal decrease in stretchability and an increase in consumption.

Performance of Industrial Pallet Wrap

Industrial Pallet Wrap performance cannot be determined by thickness alone, but by several performance criteria.

Parameter	Typical Evaluation Range	Influence On Automated Packaging
Film Thickness	12–35 microns	Determines material usage and basic protection
Elongation	100%–300%+ depending on structure	Controls stretching efficiency
Tensile Strength	Tested in machine and transverse directions	Affects resistance to tearing
Pre-Stretch Ratio	Commonly 150%–300% for machine films	Determines film consumption
Load Containment Force	Measured after wrapping	Determines pallet stability
Film Recovery	Elastic return after stretching	Maintains compression during transportation

For example, a 20-micron Industrial Pallet Wrap with optimized molecular orientation can sometimes replace a thicker conventional film because it provides higher usable stretch performance and better material utilization.

Pre-Stretch Performance: The Core Technology For Automatic Wrapping

Most automatic pallet wrappers use pre-stretch systems to extend film before application.

For example:

A machine with a 250% pre-stretch setting stretches 1 meter of film into approximately 3.5 meters of applied film length.

High pre-stretch doesn't guarantee improvements in performance; film must exhibit:

•   Controlled elongation

•   Stable recovery force

•   Uniform cross-section

•   Resistance to puncture and tear

•   Poorly designed film may exhibit poor holding force after stretching.

Yalan Pack manipulates the structure of Industrial Pallet Wrap to optimize performance after stretching. Controlling the type of raw materials and the consistency of film production helps Industrial Pallet Wrap films maintain their performance during stretching to palletize.

How Industrial Pallet Wrap Performance is Influenced by the Structure of the Film

Current stretch films are produced by multi-extrusion. Each layer of the film can have a distinct function.

Layer Function	Performance
Layer Core	Elastic layer, stretches
Layer Outer	Improves resistance to surface puncture
Layer Cling	Control of the surface adhesion between layers

Yalan Pack utilizes multi-layer stretch films to develop balanced films with the following performances:

•   Stable stretching

•   Good transparency for load viewing

•   Proper cling without high surface adhesion

•   Rolls of film proper for automatic machines

In high speed packaging the most critical factor is achieving perfect balance.

Selecting Industrial Pallet Wrap For Different Automatic Wrapping Machines

Different machines create different mechanical requirements.

Machine Type	Main Requirement	Recommended Film Characteristics
Turntable Wrapper	Stable wrapping force	Balanced stretch and recovery
Rotary Arm Wrapper	Heavy or unstable loads	Higher containment performance
Ring Wrapper	High-speed operation	Excellent consistency and low break rate

Before purchasing Industrial Pallet Wrap, manufacturers should account for:

•   Pallet weight

•   Load shape

•   Product sharp edges

•   Transportation distance

•   Environmental conditions

An example is that lightweight cartons may focus on film efficiency, while heavy industrial equipment may require better resistance to puncturing and higher holding power.

Industrial Pallet Wrap Quality Testing And Performance Verification

Professional stretch film suppliers should go beyond the cosmetic aspects of film. Industrial clients must evaluate the following:

1. Film Strength Testing

This part of the test analyzes:

•   Tensile Strength

•   Elongation

•   Tear Resistance

These methods evaluate the film's response to mechanical stress.

2. Load Stability Testing

Constructively evaluate pallet load for:

•   Movement of product

•   Stability of compression

•   Impact tolerance

3. Machine Trial Testing

Before making large purchases, companies should inspect:

•   Film break frequency

•   Film consumption per pallet

•   Line speed

Improving Packaging Efficiency With The Right Industrial Pallet Wrap

The total cost of pallet wrapping is not just the cost of the film. Consider the following:

Factor	Impact
Weight of Film Per Pallet	Material cost
Stretch Efficiency	Consumption
Break Rate	Time loss
Load Stability	Reduces loss through damage

Right Industrial Pallet Wrap can help companies achieve a good balance between material consumption and safety of goods during transport.
