Let me tell you about a pharmaceutical contract manufacturer losing $680,000 annually because stretch wrap kept tearing on their pallets.
They packaged prescription medications for major pharmaceutical brands. High-value products requiring perfect condition for distribution. Temperature-controlled cold chain throughout supply chain.
They were wrapping pharmaceutical pallets with industrial stretch wrap from commodity suppliers. Everything seemed fine in the warehouse.
But 9.4% of pharmaceutical shipments arrived at distribution centers with torn stretch wrap. Exposed products. Compromised load stability. Temperature monitoring labels displaced. Pharmaceutical customers rejecting entire pallets.
The operations manager was baffled. “We’re using heavy-duty 80-gauge film. Why does our stretch wrap keep tearing?”
A pharmaceutical packaging specialist identified three critical problems: Wrong film formulation becoming brittle in refrigerated transport. Excessive pre-stretch creating weak points. Sharp pharmaceutical case edges cutting film during transportation vibration.
They switched to pharmaceutical cold chain stretch wrap from Custom Packaging Products engineered for refrigerated pharmaceutical distribution.
Results within 60 days: Stretch wrap tears reduced from 9.4% to 1.1%. Pharmaceutical customer rejections reduced 88%. Annual savings: $598,000 from damage claim reduction.
Investment in pharmaceutical stretch wrap: $14,000 annually more than industrial film. Savings: $598,000 annually. ROI: 4,271%.
Here’s what pharmaceutical operations need to understand: stretch wrap tearing isn’t film thickness issue. It’s wrong film formulation for refrigerated pharmaceutical conditions.
So when someone asks “why does stretch wrap tear on pharma loads,” they’re really asking: what causes film failures in pharmaceutical cold chain and how can proper materials prevent tearing?
Cold Temperature Film Brittleness Causing Pharmaceutical Stretch Wrap Tears
Standard stretch wrap formulations become brittle at pharmaceutical cold chain temperatures:
Pharmaceutical Cold Chain Temperatures:
- Refrigerated transport: 34-40°F
- Some pharmaceuticals: 36-46°F strict range
- Continuous cold exposure during multi-day distribution
Standard Film Response:
- Polyethylene polymer chains lose flexibility below 45°F
- Film becomes progressively more rigid as temperature drops
- Brittle film tears easily during handling and transport
- Vibration during transportation creates stress
- Brittle film tears at stress concentration points
Why Thickness Doesn’t Solve Cold Chain Tearing: Operations managers think thicker film (80-120 gauge) prevents tearing. But thickness doesn’t address brittleness. Thick brittle film tears just as easily as thin brittle film when polymer loses flexibility.
Solution requires cold chain film formulations maintaining flexibility at refrigerated temperatures.
Pharmaceutical Case Edge Damage To Stretch Wrap
Pharmaceutical cases create unique stretch wrap challenges:
Sharp Carton Corners: Pharmaceutical cartons often have precise 90° corners. During pallet wrapping, stretch wrap conforms tightly to sharp corners. These corners create stress concentration points in film.
Transportation Vibration: Multi-day pharmaceutical distribution creates constant vibration. Film under tension rubs against sharp carton corners. Friction plus stress concentration equals film tearing.
Refrigerated Brittleness Amplification: Cold temperatures make film brittle. Brittle film has zero tolerance for corner stress. Sharp pharmaceutical case corners cut through cold-brittle film easily.
Prevention requires both cold chain film formulations AND proper corner protectors preventing film contact with sharp corners.

Excessive Pre-Stretch Creating Film Weakness
Pre-stretch percentage affects pharmaceutical stretch wrap performance:
Standard Industrial Settings:
- Pre-stretch: 250-300%
- Creates thin, aggressive film
- Works for heavy industrial products in ambient conditions
- Catastrophically weak for pharmaceutical cold chain
Cold Chain Film Mechanics: Over-stretched film (300%+) becomes extremely thin. Thin film loses mechanical strength. In refrigerated conditions, over-stretched film becomes brittle tissue paper. Any stress tears film immediately.
Optimal Pharmaceutical Pre-Stretch:
- Pre-stretch: 200-250%
- Balances economy with cold chain performance
- Maintains film thickness preventing brittleness
- Provides tear resistance in refrigeration
Equipment calibration for pharmaceutical applications requires reducing pre-stretch from industrial settings.
Pharmaceutical Cold Chain Stretch Wrap Specifications
Preventing pharmaceutical stretch wrap tears requires engineered film:
Cold Temperature Formulations:
- Polymer blends maintaining flexibility at 34-46°F
- Plasticizers preventing brittleness in refrigeration
- Materials tested under pharmaceutical cold chain conditions
Appropriate Gauge:
- 70-90 gauge for pharmaceutical applications
- Not excessively thin from over-stretch
- Adequate thickness maintaining tear resistance
Controlled Pre-Stretch:
- 200-250% optimal for pharmaceutical cold chain
- Equipment calibration for pharmaceutical applications
- Tension controls preventing over-stretch
Puncture Resistance:
- Film resisting damage from pharmaceutical case corners
- Tear propagation resistance if punctures occur
- Multi-layer films with puncture-resistant layers
Custom Packaging Products supplies pharmaceutical cold chain stretch wrap preventing tears through cold temperature engineering.
Load Protection Preventing Stretch Wrap Film Damage
Proper pharmaceutical pallet protection uses stretch wrap with corner/edge protection:
Corner Protectors: Create barrier between film and sharp carton corners. Prevent stress concentration points. Distribute film tension across edge length instead of concentrated corner contact.
Edge Protectors: Full perimeter protection preventing film contact with case edges. Maximum tear prevention for high-value pharmaceutical loads.
Combined approach: Cold chain stretch wrap PLUS corner/edge protection eliminates virtually all pharmaceutical film tearing.
