Custom Paper Bag Sizes and Handle Types: A Complete Buyer Reference

Custom paper bags are a staple for retail brands, food service operators, trade show exhibitors and luxury boutiques. Ordering the right bag requires understanding the relationship between paper weight, handle type, bag dimensions and printing method. This guide covers the key decisions a B2B buyer needs to make before sending an RFQ to a factory.

Standard Paper Bag Sizes

Paper bag sizes are typically specified in the format: Width × Depth × Height (all in mm), where Depth is the side gusset. Common sizes by industry segment:

Paper Weight (GSM) Selection

The paper weight determines load capacity, print quality and price. Key benchmarks:

• 80–90gsm: Light-duty, single use. Suitable for small boutique bags carrying items under 500g. Poor tear resistance when wet.
• 100–120gsm: Standard retail. Suitable for most gift shops, fashion retail, and food service up to 1.5kg.
• 140–157gsm: Heavy-duty retail. Suitable for carrying garments, multiple items, or for premium brands where durability matters.
• 170–200gsm: Ultra-premium. Used by luxury fashion houses. Provides excellent stiffness and an upscale feel.

For kraft paper bags, the equivalent natural kraft weights are 70–90gsm (light), 100–120gsm (standard), and 135–150gsm (heavy duty).

Handle Types Compared

• Twisted paper handle: Made from twisted kraft paper rope. Most economical. Load capacity 2–5kg. Available in matching or contrasting colour. Best for mid-market retail bags.
• Flat die-cut handle: Handle is cut into the top of the bag. No separate handle material. Lowest cost. Limited to light items under 1kg. Common for fast food bags.
• Cotton ribbon handle: Flat woven ribbon, typically 15–20mm wide. Premium feel. 5–8kg capacity. Used for luxury boutiques and high-end gift bags.
• PP rope handle: Polypropylene cord. Very strong (8–12kg capacity). Weatherproof. Common for trade show bags and grocery use.
• Paper cord handle: Twisted paper yarn. Eco-friendly. 3–6kg capacity. Increasingly popular as a sustainable alternative to cotton.

Printing Methods for Paper Bags

The printing method depends on order quantity and required print quality:

• Offset litho (sheet-fed): Highest quality, sharpest detail, accurate Pantone matching. Best for 2,000+ pieces.
• Flexo printing: Good for simple designs. Lower plate cost. Suitable for 500–5,000 pieces with 1–4 colours.
• Digital printing: No plate cost, full colour, suitable for short runs of 500–1,000 pieces. Slightly lower colour gamut than offset on uncoated stock.
