Explore our top-tier customized notebooks, canvas shopping bags, and premium paper accessories crafted to match your design identity.
Across the modern packaging supply chain, the demand for plain paper bags has evolved from a simple commodity transaction into a vital structural dynamic for sustainable retail, luxury branding, and heavy-duty industrial shipping. Environmental regulations—such as the EU's plastic tax policies and California's SB 270 legislation—have driven the global push toward reusable and recyclable paper-based containers.
For brands, plain paper bags serve as a versatile foundation. By procuring high-quality plain bags in bulk, enterprises retain the flexibility to add local branding elements, apply localized promotional stickers, or align with minimalist, high-end packaging aesthetics. This hybrid design model relies on strict physical properties: exact Grams per Square Meter (GSM) measurements, burst factor ratings, and high tensile energy absorption (TEA) to withstand modern logistics.
Custom Notebooks & Gift Packaging, Made for Your Brand.
MIJI is a China-based industry leader focusing on custom notebooks, paper bags, corporate gift sets, and paper accessories. We work with brands, wholesalers, distributors, and promotional agencies looking for high-quality, practical, brand-ready paper products.
Our core manufacturing hub is located in the Wenzhou Longgang Packaging & Printing Industrial Park, covering an area of 5,000 square meters. Equipped with advanced fully automated production machinery, we adhere to strict standards of manufacturing management to ensure consistent quality and reliable, on-time delivery.
Modern bag factories face the challenge of maintaining structural integrity across thousands of cycles. At Yiwu Miji, we implement a comprehensive manufacturing roadmap that leverages automated processes and precision control:
Our roll-fed block bottom paper bag machinery guarantees exact dimensions, clean glue application, and durable flat or twisted handle attachments with zero manual errors.
We trace all kraft paper back to its source, certifying that our pulp is sourced from responsibly managed forests. This ensures compliance with European and North American customs regulations.
Inline cameras analyze crease alignment, glue consistency, and bottom seal strength in real-time, instantly rejecting bags that fall below our structural standards.
By standardizing paper bag GSM properties—typically ranging from 80 GSM for light retail bags to 180 GSM for premium shopping bags—we tailor the mechanical properties of each run to match customer requirements. This technical precision minimizes raw material waste and ensures consistent product performance.
MIJI supports a focused range of custom paper products for overseas brands, wholesalers, distributors, promotional gift companies, and event planners. We help create coordinated products that match your brand identity, packaging needs, and project requirements.
A transparent, step-by-step process that ensures quality assurance and timely delivery for every order.
Share your product idea, target quantity, material weight, and design requirements.
Choose product style, size, GSM, handle, and packaging options.
Confirm logo placement, printing methods (foil, debossing, or flexo), and layout details.
Review digital proofs or physical pre-production samples before bulk manufacturing begins.
Advanced machinery runs production, followed by visual quality checks before packaging.
Prepare double-wall protective cartons and organize maritime, air, or express delivery.
To ensure reliable performance, we inspect and track every stage of production—from checking the moisture levels of raw paper rolls to measuring bottom seal shear strength:
Carefully selected papers and component finishes chosen for their durability and visual appeal.
Foil stamping, embossing, debossing, and multi-color screen printing options.
Clean stitching, strong spiral binding, and precise adhesive application on all products.
Physical load tests and dimensional accuracy checks conducted before shipment.
For international procurement departments, ensuring compliance with environmental standards is critical to avoiding customs friction and import penalties.
| Bag Grade / Material | Standard Grammage | Tensile Index (MD) | Recyclability Rating | Primary Application |
|---|---|---|---|---|
| Unbleached Recycled Kraft | 70 - 120 GSM | 45 - 55 Nm/g | 100% Recyclable | Supermarket Checkout, Food Takeout |
| Virgin Brown Kraft (High Strength) | 90 - 150 GSM | 70 - 85 Nm/g | 100% Biodegradable | Retail Shopping, Heavy Industrial Goods |
| Bleached White Kraft | 80 - 140 GSM | 60 - 70 Nm/g | Compostable | High-End Retail, Cosmetics Packaging |
| Coated Art Cardboard (Luxury) | 170 - 250 GSM | 90 - 110 Nm/g | Recyclable (No Foil) | Jewelry Shops, Executive Gift Bags |
Choosing the right base material ensures your brand meets local sustainability requirements:
We design custom gift boxes, notebooks, and folders to match our paper bags, creating a unified corporate gift and promotional experience.

The ideal grammage depends on your intended application. For standard retail checkout and light merchandise, 80 to 100 GSM kraft paper is standard and cost-effective. For medium retail packaging and general shopping bags, 120 GSM provides a balanced strength-to-cost ratio. High-end boutiques, heavy books, and luxury cosmetics packaging usually require 150 to 180 GSM paper with reinforced cardboard inserts at the top and base.
Our Wenzhou Longgang factory performs static weight testing and dynamic drop testing on all manufacturing runs. We utilize high-performance hot-melt and starch-based cold glues along the bottom seams. For bags with handles, we apply reinforcement patches inside the collar to spread weight across a larger surface area, preventing tearing under high tensile stress.
Yes. We specialize in coordinated packaging solutions. We can match the exact color tone, paper texture, and logo treatment (such as matching hot-foil stamping or debossing) across your custom notebooks, presentation gift boxes, and plain or printed paper bags.
We offer flexible manufacturing runs to support diverse brand needs. For standard stock sizes, our MOQs start as low as 50 pieces. Fully customized sizes, custom-dyed papers, or high-volume flexographic printing typically require an MOQ of 1,000 to 5,000 pieces to optimize machine set-up costs and reduce the unit price.
We ensure all raw materials comply with international sustainability standards. Upon request, we provide FSC-certified paper options, ensuring wood fibers are sourced from responsibly managed forests. Additionally, we avoid using heavy plastic laminations, ensuring our plain paper bags remain 100% recyclable within national municipal collection systems.
