Blown Film Technology & QC | US Industrial Standards

PE stretch film manufacturing process directly affects product performance and packaging efficiency. Advanced blown film technology can produce stretch film with >90% clarity and >500g puncture resistance.

Process Parameter	Blown Film	Cast Film	Performance Comparison
Clarity	⭐⭐⭐⭐⭐	⭐⭐⭐⭐	Blown film better
Stretch Rate	250-300%	200-250%	Blown 20% higher
Thickness Uniformity	⭐⭐⭐⭐	⭐⭐⭐⭐⭐	Cast more even
Production Cost	1.0x	1.2x	Blown more economical
Suitable Thickness	12-25μm	15-30μm	Cast for thick film

Production Key Points:

Winding Technology
Constant tension winding, core straightness <0.1mm, edge alignment <1mm to prevent wrinkles.

Material Formula
70% LLDPE + 30% LDPE optimal ratio balances stretch and toughness. Add 5% mPE for puncture resistance.

Blown Film Process
Die temperature 190-210°C, blow-up ratio 2.5:1, frost line height 4-5 times die diameter. Thickness variation <8%.

PE Transparent Packing Plastic Stretch Film vs Tape: Key Differences

Posted on 07/31/202507/31/2025 by Siliangdi@.o

Material · Function · Cost Comparison | Optimize Your Packaging

1. Material Composition

Stretch Film: Made of LLDPE (Linear Low-Density Polyethylene), offering 200-300% stretchability
Tape: Typically PP (Polypropylene) or PVC backing with acrylic/rubber adhesive

2. Primary Function

Stretch Film:
✓ Load Stabilization – Wraps entire pallets to prevent shifting
✓ Weather Protection – Waterproof & dustproof barrier
Tape:
✓ Sealing Only – Secures box openings
✓ Tamper Evidence – Void patterns show if opened

3. Performance Data

Feature	PE Stretch Film	Packing Tape
Tensile Strength	20-30MPa	15-25N/10mm
Clarity	92%+ light transmission	Opaque/Printed
Cost Efficiency	$0.02/m² (20μm)	$0.05/m (48mm)

4. Best Use Cases

Stretch Film: Pallet wrapping, warehouse storage
Tape: Carton sealing, labeling, lightweight parcels

Pro Tip: Combine both – use stretch film for stabilization + tape for secure sealing!

Colored Shipping Tape: Smart Sealing & Identification

Posted on 07/30/202508/25/2025 by Siliangdi@.o

US E-commerce Logistics Management Standard

Colored shipping tape is reshaping logistics management for US e-commerce. This simple color-coding system can improve sorting efficiency by 40% and reduce mis-shipments by 30%.

Color Code	Application	Features	Cost Benefit
Red	Expedited Orders	Instant ID, priority handling	Reduce delay costs
Blue	Standard Orders	Efficient sorting	Lower labor cost
Green	Eco Orders	Sustainable material	Brand value boost
Yellow	Fragile Items	Warning标识	Reduce damage cost
Black	High-value Goods	Discreet packaging	Theft prevention

Security Enhancement
Special colors content value, effectively deterring internal theft.

Visual Management
Color coding enables instant identification. Sorters can categorize packages without reading labels, ideal for peak season.

Brand Differentiation
Custom colored tape acts as mobile billboards, increasing brand recall by 18% and strengthening visual identity.

Start with a 4-color system: Red (urgent), Blue (standard), Yellow (fragile), Green (returns). Begin with high-value products and peak seasons, then expand to all categories. Choose acrylic adhesive for all-weather performance.

Painter’s Tape Guide: Multi-Surface Precision Solutions

Precision selection of painter’s tape directly affects construction quality and efficiency. Different colors represent different adhesion levels and suitable surfaces. Correct selection can improve work efficiency by 50%.

Color Code	Adhesion Level	Suitable Surfaces	Dwell Time	Cost Index
Light Blue	Ultra-Low (0.5-1.0N)	Latex paint, wallpaper	≤60min	1.0x
Standard Blue	Low (1.0-1.5N)	Wood, metal paint	≤24hr	1.2x
Green	Medium (1.5-2.0N)	Textured surfaces	≤48hr	1.5x
Yellow	High (2.0-2.5N)	Tile, glass	≤72hr	1.8x
Red	Ultra-High (2.5-3.0N)	Outdoor, high temp	≤7days	2.2x

Technical Selection Points:

Surface Adaptability
Porous surfaces (e.g., drywall) require medium-high adhesion tape. Non-porous surfaces (e.g., glass) need low adhesion to prevent residue.
Time Control
Select tape based on project duration: 30min fine work uses light blue, >24hr projects need green or higher.
Environmental Factors
High temperature (≥35°C) requires heat-resistant red tape. Humid environments need professional moisture-resistant products.
