Stretch Film: Types, Uses & Benefits

Stretch film, also known as stretch wrap, is a highly stretchable plastic film used to wrap and secure products on pallets for storage and transportation.

It is made primarily from LLDPE (Linear Low-Density Polyethylene) and is designed to cling tightly to itself without adhesive, creating a stable, dust-proof, and moisture-resistant layer around palletized goods.

Stretch film is widely used in warehouses, logistics centers, manufacturing facilities, and retail distribution to unitize loads and protect products during shipping.

I. Main Types of Stretch Film

1. Hand Stretch Film

Designed for manual application using a handheld dispenser or by hand.

Best for:

• Small to medium volume packing

• Warehouses without automatic wrapping machines

• Irregular or odd-shaped loads

Benefits:

• No machine required – low upfront cost

• Easy to use with minimal training

• Available in various widths and thicknesses

Common thickness: 12 – 20 microns

2. Machine Stretch Film

Designed for use with automatic or semi-automatic stretch wrapping machines.

Best for:

• High-volume pallet wrapping

• Consistent, repeatable loads

• Distribution centers and large warehouses

Benefits:

• Higher stretch capacity (up to 300%)

• Faster wrapping speed

• Less film usage per pallet – cost savings

Common thickness: 15 – 30 microns

3. Pre-Stretched Film

Pre-stretched during manufacturing, requiring less force to apply.

Best for:

• Manual wrapping where worker fatigue is a concern

• Light to medium loads

• Ergonomic workspaces

Benefits:

• Easier to apply – reduces worker strain

• Consistent stretch performance

• Less film waste

4. Colored Stretch Film

Available in black, blue, red, yellow, green, and other colors.

Best for:

• Load identification and color coding

• UV protection for light-sensitive products (black film)

• Security – concealing valuable goods

Benefits:

• Easy visual sorting by department or destination

• Adds a layer of security

• Available in hand and machine grades

5. VCI Stretch Film

Contains Vapor Corrosion Inhibitors to protect metal products from rust.

Best for:

• Metal parts, coils, and machinery

• Long-term storage or ocean shipping

• High-humidity environments

Benefits:

• Prevents rust without oil or coating

• Clear film allows visual inspection

• Saves time vs. traditional rust protection methods

6. Anti-Static Stretch Film

Designed for electronic or sensitive components.

Best for:

• Electronics packaging

• Automotive components

• Clean room environments

Benefits:

• Prevents static buildup

• Protects sensitive components from damage

• Clear or colored options available

II. Key Features to Consider

III. Stretch Film Usage Scenarios

Warehouse & Distribution Center

Challenge: High-volume pallet wrapping for shipping.

Recommendation: Machine stretch film with high stretch capacity (250-300%)

Why: Maximizes efficiency and reduces film cost per pallet.

Retail Backroom

Challenge: Small loads, manual wrapping by store staff.

Recommendation: Hand stretch film or pre-stretched film

Why: Easy to use, no machine needed, reduces worker fatigue.

Metal Parts Export

Challenge: Long ocean transit with risk of rust.

Recommendation: VCI stretch film

Why: Prevents corrosion without additional rust protection steps.

Outdoor Storage

Challenge: Sun exposure and weather.

Recommendation: Black or UV-resistant stretch film

Why: Protects products from UV damage and conceals contents.

Electronics Manufacturing

Challenge: Static damage to sensitive components.

Recommendation: Anti-static stretch film

Why: Prevents electrostatic discharge (ESD) damage.

V. Frequently Asked Questions

Q1: What is the difference between hand stretch film and machine stretch film?
A1: Hand film is designed for manual application with lower stretch capacity (150-200%). Machine film has higher stretch capacity (250-300%) and is designed for use with wrapping machines.

Q2: What thickness should I choose?
A2:

• 12-15 microns: Light loads, uniform shapes

• 18-23 microns: Standard loads, most common

• 25-30 microns: Heavy loads, sharp corners, irregular shapes

Q3: How do I calculate how much film I need per pallet?
A3: Contact us with your pallet size and wrap pattern. We can provide a calculation based on film width, stretch percentage, and number of wraps.

Q4: Is stretch film recyclable?
A4: Yes. Most stretch film is made from LLDPE and can be recycled through industrial recycling programs. Check with local recycling facilities for acceptance.

Q5: Can you print on stretch film?
A5: Yes. Custom printing (logo, handling instructions, barcode) is available, typically on the film core or as a printed layer. Minimum order quantities apply.

Q6: What is pre-stretched film?
A6: Pre-stretched film is stretched during manufacturing, so it requires less force to apply manually. It is easier on workers but has less remaining stretch capacity.

Q7: How should stretch film be stored?
A7: Store in a cool, dry place away from direct sunlight and heat sources. Avoid temperatures above 40°C (104°F) to prevent film degradation.

Q8: Do you offer custom roll widths?
A8: Yes. Standard widths are 450mm and 500mm. We can produce custom widths based on your requirements. Minimum order quantity applies.

Q9: What is VCI stretch film?
A9: VCI (Vapor Corrosion Inhibitor) stretch film releases a vapor that forms a microscopic protective layer on metal surfaces, preventing rust during storage and shipping.

Q10: Can I get samples for testing?
A10: Yes. We provide free samples for testing. Contact us with your application details and we will recommend the right film type.
