Product Description
Kraft Paper Handled Takeaway Bags
Professional packaging solutions for food delivery, milk tea, bakery, and gift applications with custom logo printing capabilities.
Product Overview
Our kraft paper handled takeaway bags undergo rigorous engineering testing for material selection, structural mechanics, and handle reinforcement systems. Designed to withstand heavy loads and rough handling in food delivery, milk tea, bakery, and gift scenarios.
Technical Specifications
Virgin Kraft Paper Mechanical Advantages
Selected long-fiber softwood pulp kraft paper with 2.5-3.0mm average fiber length provides superior strength:
- MD Tensile Strength: ≥ 4.5kN/m (120g specification)
- Bursting Strength: ≥ 350kPa (120g specification)
- Tearing Strength: ≥ 800mN (MD direction)
Kraft paper demonstrates 35% higher tear resistance than ordinary white cardstock, maintaining structural integrity even with sharp-edged containers or in humid environments.
Square Bottom Structure Mechanics
Machine-precision folded square bottom design optimizes load distribution:
- 40% increased bottom load-bearing area with uniform stress distribution
- Enhanced longitudinal support preventing content sagging and deformation
- 25%-30% expanded volume capacity compared to traditional tapered bottom bags
Static load tests confirm size #12 bags (240×320×130mm) loaded with 8kg for 24 hours show no bottom cracking or deformation.
Handle System Load-Bearing Solutions
| Handle Type | Material Specifications | Fixing Method | Dynamic Load Capacity | Applicable Scenarios |
|---|---|---|---|---|
| Kraft Paper Twisted Handle | 3-ply virgin paper rope, diameter 4mm | Double rivets + hot melt adhesive | ≤ 5kg | Milk tea, bakery, light retail |
| Cotton Rope Handle | 16-ply combed cotton, diameter 5mm | Double rivets + reinforcement patch | ≤ 8kg | Food delivery, multiple drinks |
| PP Webbing Handle | Width 15mm, thickness 1.2mm | Four-hole rivets + hot melt adhesive | ≤ 12kg | Heavy retail, beverages, gift boxes |
All handle connections undergo simulated repeated lifting tests (80 times/minute for 2 continuous hours) ensuring no loosening or detachment under full load.
Custom Printing Technical Specifications
Bag surface calendered to 30-40s smoothness ensures clear dot reproduction:
- Printing Precision: Minimum reproducible line width 0.1mm, dot reproduction rate ≥95%
- Registration Error: ≤0.2mm, precise multi-color registration
- Color Control: ΔE < 1.5 (within batch), Pantone matching
- Abrasion Resistance: Printed layer tested under 4lb pressure friction, 50 cycles with no visible wear
Supports offset printing, flexo printing, hot stamping, embossing/debossing, and other processes.
Environmental Adaptability Testing
Extreme usage scenario simulations:
- High Temperature & Humidity: 24 hours at 40°C/85% RH, paper stiffness retention ≥85%
- Low Temperature Brittleness: Drop test after freezing at -10°C for 4 hours, no brittle cracking
- Water Resistance: Water droplets wiped from surface, no penetration or deformation within 30 minutes
