Improving packaging efficiency: Tips for using Manual Stretch Film

Introduction

Manual Stretch Film plays a crucial role in warehouse, logistics, and transportation operations. Proper usage not only secures goods but also saves time, labor, and materials. This article provides practical tips to improve packaging efficiency using Manual Stretch Film.

Selection of the Right Manual Stretch Film

Thickness and Strength

Choose the right thickness according to the weight and shape of your goods.

• 15μm–20μm: Suitable for light to medium loads.
• 23μm or higher: Ideal for heavy or irregular items.

Stretchability and tear resistance are critical for reducing film breakage and improving efficiency.

Width and Length

• Width: Standard sizes like 500mm or 450mm help cover goods faster.
• Length: Longer rolls reduce frequent replacement, saving time.

Material and Functionality

• High-elasticity film: Better for irregular loads.
• High-adhesion film: Ideal for smooth surfaces.
• Additional functions: Anti-static, UV protection, or recyclable materials.

Correct Wrapping Posture and Method

Film Grip

Use either a hand grip or dispenser to hold the film tightly against the goods. Proper grip ensures even coverage and prevents wastage.

Stretching Technique

• Pull the film slightly before wrapping to avoid slack.
• Avoid excessive force that may tear the film.

Wrapping Sequence

• Bottom → Middle → Top: Ensures stability.
• Cross wrapping adds extra support and prevents sliding or collapsing.

Efficiency-Boosting Tips

Pre-cut Film

Cut the film to approximate length according to item size. This reduces on-site adjustments.

Two-Person Collaboration

For large or bulky goods, two operators can wrap simultaneously, improving speed by 50% or more.

Use of Film Dispenser

A roller or dispenser keeps the roll rotating smoothly and reduces hand fatigue.

Proper Stretch and Tension Control

• Too tight → Film may tear.
• Too loose → Poor stability.
• Find the optimal tension to minimize waste.

Common Problems and Solutions

Film Tearing or Slipping

• Check thickness, material, and stretching method.

Uneven Wrapping

• Improve technique or use a dispenser for better control.

Material Waste

• Optimize stretch ratio and number of layers to save costs.
