What Are the Classifications of Packaging? A Comprehensive Analysis by Material, Application, and Structure

Three Dimensions of Packaging Classification

Packaging classification is generally divided into three dimensions: material, application, and structure. Each dimension corresponds to a different selection logic: the material dimension determines physical performance and cost range, the application dimension determines compliance requirements and process focus, and the structure dimension determines opening method and transportation efficiency. Only the intersection of all three dimensions can completely position a packaging type.

For example, a cosmetic gift box belongs to the paper gift box category from the material dimension, belongs to cosmetic packaging from the application dimension, and belongs to the top-and-bottom box category from the structure dimension. The three classification labels exist simultaneously, but each label provides a different information dimension.

First Dimension: Classification by Material

By material, packaging can be divided into five categories: paper, plastic, metal, glass, and composite materials. Paper packaging is the most common type in the industry, including corrugated cartons, paper boxes, paper bags, and pulp molding. Plastic types include plastic bags, plastic boxes, blister boxes, and shrink film. Metal types are mainly tinplate cans and aluminum foil bags. Glass types are mainly bottles and test tubes. Composite materials are combinations of two or more materials, such as aluminum-plastic composite film and paper-plastic composite boxes.

Paper packaging has many sub-types. Corrugated cartons are divided by flute type into E-flute, B-flute, C-flute, and double-wall corrugated. Paper boxes are divided by face material into white cardboard boxes, coated paper boxes, and specialty paper boxes. Paper bags are divided by material into kraft paper bags, white cardboard bags, and coated paper bags. Pulp molding is environmentally friendly packaging formed from waste paper pulp, commonly seen in egg trays and industrial cushioning parts.

Plastic packaging also has many sub-types. PE bags are commonly used for food bags and garbage bags. PP boxes are commonly used for food containers and lunch boxes. PET bottles are commonly used for beverages and cosmetics. PVC shrink film is commonly used for batteries and bottle cap seals for wine. Blister boxes are commonly used for 3C accessories and hardware tools.

Second Dimension: Classification by Use

By use, packaging can be divided into eight major categories: food packaging, cosmetic packaging, pharmaceutical packaging, medical device packaging, electronic product packaging, gift packaging, transport packaging, and industrial packaging. Compliance requirements and process focus vary significantly across these categories.

Food packaging must comply with the GB 4806 series of food contact standards. Cosmetic packaging must comply with the relevant requirements of the cosmetic labeling management measures. Pharmaceutical packaging must comply with the Pharmaceutical Administration Law and the relevant GMP regulations. Medical device packaging must comply with ISO 11607-1 and the YY/T 0698 series standards.

Electronic product packaging focuses on anti-static, moisture-proof, and cushioning properties. Common practices include EPE pearl cotton or air column bags combined with corrugated outer cartons, and some high-end products also include moisture barrier bags and desiccants. Gift packaging focuses on visual presentation and unboxing experience, commonly using rigid lid-and-base boxes, drawer boxes, and book-style boxes combined with hot stamping, spot UV, and embossing processes.

Transport packaging and industrial packaging focus more on load-bearing capacity and cost. GB/T 6543-2008 provides clear specifications for the classification, dimensions, compressive strength, and moisture content of corrugated cartons used for transport packaging. Export transport packaging should also comply with ISPM 15 requirements for the treatment of wood packaging materials.

Third Dimension: Classification by Structure

By structure, packaging can be divided into eight major categories: folding boxes, gift boxes, drawer-style boxes, hinged boxes, irregular-shaped boxes, display boxes, plastic packaging, and bags. Each category corresponds to a different opening method and forming process.

Folding boxes are the most frequently used type in the industry, including mailer boxes, folding color boxes, and double-open boxes. Mailer boxes are integrally folded and formed, most commonly seen in e-commerce scenarios. Folding color boxes are made of thinner paper and are suitable for cosmetics and small accessories. Double-open boxes are formed by gluing, with a load-bearing capacity of 10 to 40 kilograms, suitable for medium-sized products.

Gift boxes are commonly used for high-end products, including top-and-bottom lid boxes, book-style boxes, and flip-top boxes. Top-and-bottom lid boxes have separated upper and lower lids, offering a strong sense of ceremony when closed. Book-style boxes open like a book, commonly seen in high-end gifts. Flip-top boxes have the lid connected to the box body via hinges, making them easy to open and close.

Drawer-style boxes are boxes with a drawer structure, including drawer boxes and nested boxes. Hinged boxes are opening and closing methods other than flip-top and book-style, including flip-top boxes, magnetic closure boxes, and snap-fastener boxes. Irregular-shaped boxes are non-conventional shapes such as round and polygonal, including cylindrical boxes and hexagonal boxes. Display boxes are box types used for shelf display, including window boxes and showcase boxes.

Cross-Method of Three Dimensions

The cross-method of three dimensions involves first determining the application, then selecting the structure, and finally choosing the material. Application determines the regulatory boundaries, structure determines the box-opening method and transportation efficiency, and material determines the physical performance and cost.

For example, in a cosmetics gift box project, the application is cosmetics packaging, which needs to comply with the cosmetics labeling management measures and food contact-related standards (for some inner layers). In terms of structure, a lid-and-base box is chosen, as its closing ceremony feels strong and suits high-end brands. In terms of material, gray board paper is selected as the skeleton, with coated paper or specialty paper laminated on the surface, and processes including hot stamping and partial UV coating.

For example, in an e-commerce shipping box project, the application is transportation packaging, which needs to comply with the basic standards for corrugated cartons. In terms of structure, a mailer box is chosen, as it folds into shape in one piece and offers high transportation efficiency. In terms of material, E-flute or B-flute corrugated paperboard is selected, with the flute type and liner paper grammage chosen according to the product weight.

Common Combination Types

Food gift boxes: paper + food packaging + lid-and-base box. Commonly use grey board as the frame, with coated paper or specialty paper laminated on the surface, and food-grade PE bags or aluminum foil bags added as the inner layer. Cosmetic gift boxes: paper + cosmetic packaging + lid-and-base box or drawer box. Commonly use grey board as the frame, with gold foil stamping and partial UV coating. Wine boxes: paper or metal + wine packaging + lid-and-base box or cylindrical box. High-end wine boxes commonly use rigid paperboard combined with velvet fabric lining.

E-commerce apparel boxes: paper + shipping packaging + mailer box. E-flute or B-flute corrugated board, four-color water-based printing, with glossy film lamination. 3C accessory boxes: paper + electronic product packaging + mailer box or drawer box. E-flute corrugated board paired with EPE pearl cotton inner tray, with some adding moisture-proof bags. Industrial parts boxes: paper + industrial packaging + double-wall corrugated RSC box. BC double-wall corrugated can bear up to 80 kilograms.

Common Misconceptions in Material-Based Classification

Myth 1: Paper packaging is always environmentally friendly. Paper packaging has a high recycling rate, but once some paper packaging is laminated or combined with other materials, recycling becomes significantly more difficult. Myth 2: Plastic packaging is always not environmentally friendly. The recycling system for plastic packaging is constantly improving, with the recycling rates of PE, PET, and PP increasing year by year. The environmental restrictions on PVC mainly stem from phthalates rather than the recycling process itself.

Myth 3: Metal and glass packaging are always more expensive than paper. This depends on the product size and production volume. Small-batch gift boxes are more economical with paper, while large-batch canning is more economical with metal and glass. Material selection involves comprehensive trade-offs, rather than a simple comparison of environmental friendliness or cost.

Compliance Boundaries by Application Category

Food packaging has the strictest compliance boundaries. Paper and paperboard in direct contact with food should comply with GB 4806.8-2022, and plastics should comply with GB 4806.7-2023. The number of packaging layers should also comply with GB 23350-2021. Cosmetic packaging requires verification of ingredient labeling, allergen marking, and production information. Pharmaceutical packaging requires verification of the Pharmaceutical Administration Law and relevant GMP regulations.

Medical device packaging has the most unique compliance boundaries. ISO 11607-1 specifies requirements for packaging materials, design, and testing of terminally sterilized medical devices, while ISO 11607-2 specifies requirements for packaging validation. Common sterilization methods include ethylene oxide sterilization, gamma radiation sterilization, and high-temperature steam sterilization, each with different temperature resistance requirements for packaging materials.

How to Quickly Identify Packaging Types

When quickly identifying packaging types, follow three steps. First, define the use case to set compliance boundaries and process priorities. Next, choose the structure to determine opening methods and shipping efficiency. Finally, select the material based on physical performance and cost range. This approach applies to most packaging projects.

Key Points Review

• Packaging classification is divided into three dimensions: material, application, and structure.
• The material dimension determines physical performance and cost range.
• The application dimension determines compliance requirements and process focus.
• The structure dimension determines opening method and transportation efficiency.
• The three dimensions must intersect to fully define a packaging type.

Clarifying the boundaries of the three dimensions provides clearer direction for packaging selection, budget allocation, and compliance review. This also avoids the common mistake of mixing classification labels from different dimensions in evaluation.
