Material Classification

We have paper bag material as follows. Material determines the bag's strength, texture, water resistance, and printability, serving as the foundation for functionality.

Material Type	Core Features	Grammage Range (gsm)	Typical Applications	Advantages & Limitations
Kraft Paper	Natural brown color; high tensile strength; eco-friendly (recyclable/biodegradable).	120-300	Heavy-duty shopping bags, grocery bags, industrial packaging.	√ Durable, cost-effective. × Limited color options (natural/brown).
White Cardstock	Bright white; smooth surface; excellent printability; medium stiffness.	200-400	Luxury gift bags, brand promotional bags, high-end packaging.	√ Vibrant color reproduction. × Less water-resistant than coated paper.
Coated Paper (Art Paper)	Smooth, glossy surface (coated with kaolin clay); high gloss; suitable for fine printing.	150-350	Fashion packaging, cosmetic bags, premium product displays.	√ Stunning visual effects. × Prone to scratching; poor water resistance (unlaminated).
Art Paper (Specialty)	Textured/embossed surfaces (e.g., linen, felt, marble); decorative patterns.	180-300	Creative gift bags, boutique packaging, artistic displays.	√ Unique tactile/visual appeal. × Higher cost; limited print compatibility.
Laminated Paper	Surface coated with PE/CPP film (glossy/matte); waterproof, oil-resistant, and tear-resistant.	200-400	Food packaging (e.g., fast food, bakery), wet product bags.	√ Multi-functional (water/oil proof). × Less eco-friendly (non-degradable film).
Recycled Paper	Made from post-consumer waste; eco-friendly (FSC-certified); slightly rough texture.	100-300	Eco-conscious shopping bags, corporate social responsibility (CSR) packaging.	√ Sustainable; lower cost than virgin paper. × Weaker strength; limited color vibrancy.

Process Classification (Printing & Lamination)

We have printing techniques as follows. Processes enhance aesthetics, functionality, and brand identity.

A. Printing Techniques

Printing Method	Core Features	Best For Materials	Typical Effects	Cost Level
Offset Printing	High precision (fine details); wide color gamut; suitable for large runs.	Coated paper, art paper	Sharp text/logo, gradient colors, high resolution.	$$$
Flexography	Fast production; low cost; ideal for simple patterns (e.g., logos, solids).	Kraft paper, recycled paper	Bold, flat colors; suitable for bold designs.	$$
Screen Printing	Thick ink layer; textured effects; suitable for special inks (e.g., metallic, fluorescent).	Cardstock, specialty art paper	Opaque colors, 3D raised effects.	$$$
Digital Printing	No plate setup; short runs; customizable (variable data).	Most papers (especially recycled)	Photorealistic images; on-demand production.	$$$

B. Lamination Techniques

Lamination Type	Core Features	Best For Materials	Typical Effects	Eco-Friendliness
Glossy Lamination	Shiny surface; enhances color saturation; protects prints from scratches.	Coated paper, art paper	High-gloss, vibrant visuals.	Low (PE film non-degradable)
Matte Lamination	Non-glossy surface; reduces glare; gives a premium, understated look.	Cardstock, specialty art paper	Soft touch, elegant matte finish.	Low (PE film non-degradable)
Eco-Film Lamination	Made from PLA (polylactic acid) or recycled PET; biodegradable/compostable.	Recycled paper, kraft paper	Water-resistant; eco-friendly alternative.	High

Usage Classification

Usage dictates material-process combinations based on functional and aesthetic requirements.

Usage Type	Key Requirements	Recommended Material + Process	Example Scenarios
Grocery/Shopping Bags	High strength (load-bearing); eco-friendly; cost-effective.	Kraft paper (250-300gsm) + Flexography (simple logo).	Supermarket checkout bags, farmers' market bags.
Food Packaging Bags	Waterproof, oil-resistant, food-safe (FDA-compliant); odorless.	Laminated paper (PE film) + Screen Printing (solid colors).	Fast food takeout bags, bakery pastry bags.
Luxury Gift Bags	Aesthetic appeal (glossy/matte); tactile texture; brand visibility (logo).	White cardstock (300gsm) + Offset Printing (metallic ink) + Matte Lamination.	High-end brand gift boxes, wedding favor bags.
Brand Promotional Bags	Customizable (logos, slogans); eye-catching; reusable.	Art paper (250gsm) + Digital Printing (photorealistic images) + Glossy Lamination.	Corporate events, trade shows, customer giveaways.
Eco-Conscious Bags	Recyclable/biodegradable; minimal plastic; sustainable sourcing.	Recycled paper (200gsm) + Digital Printing (water-based ink) + Eco-Film Lamination.	Brand CSR campaigns, zero-waste stores.
