Custom Eco Friendly Kraft Paper Bag Square Bottom Design Sturdy
Handles for Catering and Retail
Product Description:
In the fast-paced era of food delivery and retail consumption, the
durability of a paper bag often directly influences consumers'
perception of brand quality. Our custom eco-friendly kraft paper bag is engineered from material selection, bottom structure, to handle
reinforcement—every detail undergoes rigorous engineering design,
providing businesses with a packaging solution that truly
withstands heavy loads and rough handling.
More Than Just a Bag, It's Reliable Carrying Capacity:
Virgin Kraft Material, Naturally Strong
Selected long-fiber virgin wood pulp eco-friendly kraft paper offers excellent tear resistance and tensile strength. Unlike
ordinary white cardstock that softens when exposed to moisture,
kraft paper's natural moisture-resistant and tear-resistant
properties maintain its shape in various environments such as
refrigeration or room temperature. More importantly, the paper is 100% recyclable and biodegradable, helping your brand balance packaging performance with
environmental responsibility.
Precision Square Bottom, Breakthrough in Capacity and Stability
We've eliminated the shortcomings of traditional paper bags prone
to bottom collapse and instability. The square bottom design, formed through precision folding technology, creates a flat and
spacious base with even stress distribution. When opened, the
internal space significantly increases compared to ordinary bags,
easily accommodating square meal boxes, cylindrical beverage
bottles, or multiple irregular retail items. Most importantly, the
square bottom structure keeps the bag stable as a rock on tables,
counters, or in delivery boxes, preventing tipping and avoiding
product spillage risks.
Reinforced Handle System, Challenging Higher Loads
Handle durability is the core indicator of paper bag quality. We
offer multiple sturdy handle solutions:
Thickened Cotton Rope Handles: Soft and comfortable touch, reinforced with double rivets,
single-point load capacity up to 8kg+.
Widened PP Webbing Handles: Crisp and durable, suitable for long-term carrying of heavier
items.
Natural Paper Rope Handles: Seamlessly integrated with the bag body for visual unity, also
reinforcement-treated.
All handles undergo laboratory simulated tensile testing, ensuring
repeated lifting under full load without breakage or debonding,
giving consumers absolute peace of mind.
Data-Driven Load Capacity, Tested Performance
Taking our common size #4 (Width 220 × Height 320 × Bottom Width
130mm) as an example:
Static Load Test: 15kg fully loaded for 24 hours, no bottom
cracking, no handle detachment.
Dynamic Lifting Test: 8kg fully loaded, lifted 100 times
repeatedly, no loosening at handle connections.
Each batch undergoes sampling tensile testing before shipment,
ensuring consistent and stable quality.
Full-Dimension Customization, Freedom from Grammage to Printing
Comprehensive customization services from paper to process:
Paper Customization: Multiple grammage options from 80g to 150g, adapting to
lightweight to heavy-duty needs.
Size Customization: From mini dessert bags to large shopping bags, dimensions
adjustable as required.
Handle Customization: Free choice of three handle types mentioned above, length and
color also customizable.
Printing Customization: Bag surface calendered for smoothness and fineness, supporting
1-4 color offset printing, flexo printing, hot stamping,
embossing/debossing, and other processes. Brand logos and patterns
can be clearly presented without detail distortion.
Storage Friendly, Open and Use
Bags are flat-folded when shipped, tightly stacked, saving up to
70% storage space. In-store, simply open the bottom for quick
forming, no complex assembly required, significantly improving
packing efficiency during peak hours.
