Complete Guide to Packaging Printing Materials: Cardboard, Synthetic Paper & All Corrugated Flute Types

With the booming development of global cross-border trade, packaging materials directly determine printing quality, transportation protection, export compliance, and brand image. Many overseas buyers, when customizing color boxes, tote bags, and shipping cartons, are unclear about the applicable scenarios for various types of paper, synthetic films, and corrugated board. Choosing the wrong material can easily lead to problems such as printing color differences, transportation damage, cost overruns, and non-compliance with customs and environmental regulations.

As a one-stop export packaging and printing factory, this article comprehensively outlines our factory's full range of mass-produced printing substrates: conventional paper printing materials, PVC/PET/PE/PP synthetic specialty papers, and a full range of single and double-layer corrugated cardboard. It breaks down the characteristics, advantages, and applicable export products of each material to help overseas clients quickly and accurately select materials and reduce customization trial-and-error costs.

Part 1: Common Paper Printing Substrates (White Cardboard / White Board Paper / Coated Paper / Kraft Paper)

1. White Cardboard (Ivory Board / SBS)

Material Characteristics: Multi-layer coated paperboard made from pure virgin wood pulp, high whiteness and smoothness on both sides, strong stiffness, excellent folding resistance, and excellent color reproduction. Suitable for printing with all colors of environmentally friendly water-based inks. Food-grade white cardboard can pass FDA and LFGB export food compliance certifications.

Applications: High-end cosmetic gift boxes, electronic product color boxes, luxury brand tags, clothing packaging boxes, baked goods outer packaging, and boutique tote bags.

Export Advantages: High-end texture highlights brand image; the preferred material for retail packaging in European and American supermarkets; supports a full range of post-processing including lamination, hot stamping, and embossing.

2. White Board Paper (Grey Back Chipboard, WLC)

Material Characteristics: White printing coating on the front, grey recycled pulp on the back; high cost-performance ratio, sufficient stiffness, stable printing performance, high proportion of recycled materials, and meets EU environmental recycling standards.

Applications: Mid-range daily chemical packaging boxes, toy color boxes, general small commodity outer packaging, and inner lining paperboard for laminated gift boxes.

Foreign Trade Advantages: Controls packaging costs, suitable for large-volume export orders of affordable fast-moving consumer goods.

3. Coated Art Paper

Material Characteristics: Finely coated surface, high gloss, delicate and saturated image; available in glossy and matte coated versions; thinner than cardstock, excellent for printing photo-quality images.

Applicable Scenarios: Product brochures, instruction manuals, posters, lightweight color boxes, cosmetic sample packaging.

Foreign Trade Advantages: Strong color expression, suitable for brand promotional materials requiring high-definition realistic printing.

4. Kraft Paper

Material Characteristics: Unbleached virgin wood pulp, strong toughness, tear resistance, tensile strength, natural vintage texture; available in yellow kraft, white kraft, and recycled kraft paper; 100% recyclable and biodegradable, a mainstream material for green and environmentally friendly packaging.

Applicable Scenarios: Eco-friendly tote bags, clothing hang tags, e-commerce express envelopes, minimalist food packaging, agricultural product packaging.

Foreign trade advantages: Aligns with global sustainable consumption trends, adapts to various countries' plastic restriction and environmental protection policies, and lightweight logistics reduces ocean freight costs.

Part Two: PVC/PET/PE/PP Synthetic Specialty Paper (Waterproof and Tear-Resistant Special Material)

Unlike ordinary paper, synthetic paper is waterproof, oil-proof, tear-resistant, and resistant to high and low temperatures, making it suitable for outdoor, humid, and long-term wear-resistant export packaging needs. All support environmentally friendly solvent-free printing processes.

1. PET Synthetic Paper: High transparency, strong rigidity, stable temperature resistance, and UV protection. Suitable for high-end transparent windowed boxes, waterproof product labels, and outdoor product hang tags. Food-contact grade PET can be used for food packaging.

2. PP Synthetic Paper: Lightweight and flexible, resistant to bending and does not whiten, acid and alkali resistant. Cost-effective synthetic paper, widely used for wine labels, waterproof stickers for daily chemical products, and waterproof express delivery hang tags for e-commerce.

3. PE Synthetic Paper: Soft and highly extensible, waterproof and moisture-proof. Suitable for flexible packaging, disposable waterproof labels, and cold chain fresh product labeling.

4. PVC Synthetic Paper: Smooth surface, wide color gamut for printing; rigid PVC is used for display boards and product labels; flexible PVC is used for waterproof self-adhesive labels; for export, low-phthalate compliant PVC material can be provided, meeting European and American toy and daily necessities testing standards.

Part Three: Detailed Explanation of All Corrugated Board Specifications (Single-flute A/B/C/E/F/G + Combined Double-flute AB/BC/Double E/Double F)

Corrugated board is a core material for export transport packaging. It relies on a sandwich-like corrugated structure for cushioning and compression resistance. Different flute heights and numbers correspond to different protection and printing needs. The following is a complete model compatibility guide:

Type A corrugated: Highest flute height, best cushioning and shock absorption performance in the industry, strong vertical compression resistance; disadvantages include uneven surface, resulting in less refined printing effects.

Suitable for: Fragile goods, glass and ceramics, handicrafts, and cushioned transport outer boxes for large equipment.

Type B corrugated: Dense and flat flutes, puncture resistance, good flat compression resistance, high printing precision, and less prone to deformation when stacked.

Suitable for: Canned goods, small hardware items, standard e-commerce express boxes, and retail display boxes.

Type C corrugated: Combining the cushioning of A-flute and the flatness of B-flute, offering balanced performance, the strongest versatility, and the best value for money.

Suitable for: Daily necessities, furniture accessories, and general industrial goods transport boxes.

Type E corrugated: Thin yet sturdy, smooth surface, suitable for high-definition four-color printing, a replacement for cardboard for small color boxes.

Suitable for: 3C digital gift boxes, cosmetic shipping boxes, and small boutique retail packaging.

Type F corrugated : Ultra-thin and lightweight, with a thickness close to cardboard, taking up little storage space.

Suitable for: Fast food boxes, small digital accessory packaging, and lightweight display boxes.

Type G corrugated: The thinnest corrugated board on the market, with a texture close to cardboard, offering extremely smooth printing, specifically designed for lightweight, high-end micro-packaging.

Suitable for: high-end beauty sample boxes, inner packaging of small electronic products, and luxury mini gift boxes.
