Types of Packaging: Layers and Materials
Updated November 13, 2026
"Types of packaging" means two different things, and both matter when you choose yours. One is the layer, primary, secondary, or tertiary, which describes a package's job in the chain from product to shelf to shipment. The other is the material, which decides protection, feel, and cost. This guide covers both, with what each is best for.
By layer: primary, secondary, tertiary
Packaging layers: the three roles packaging plays from product to shipment: primary (directly contains the product), secondary (groups and presents it), and tertiary (protects it in bulk transit).
Using a skincare brand as an example, the layers stack like this:
| Layer | Example | Main job |
|---|---|---|
| Primary | Glass bottle with a secure cap | Contains the product; carries the key info and branding |
| Secondary | Printed paperboard carton | Presents the bottle, adds shelf appeal and detail |
| Tertiary | Corrugated case of multiple cartons | Protects stock during delivery and handling |
Not every product needs all three. A small direct-to-customer item might use one mailer that does the job of both grouping and transport, so decide what each piece is actually for.
By material
Each material trades protection, feel, sustainability, and shipping weight differently.
| Material | Strengths | Best for |
|---|---|---|
| Cardboard and paper | Cost-effective, recyclable, familiar, good structure | General retail and lightweight goods |
| Plastic | Durable, good moisture and leak barrier, light to ship | Liquids and moisture-sensitive items |
| Metal | Strong, blocks light and air; long lifecycle | Beverages, paints, sensitive contents (adds weight) |
| Glass | Premium feel, reusable, inert | Food, drink, premium products (fragile, heavy) |
| Biodegradable | Decomposes naturally, strong eco signal | Eco-focused brands, low-waste unboxing (may need cushioning) |
How to choose
Match the material to what the product actually needs. Does it leak or absorb moisture? Lean plastic or a lined carton. Is it fragile? Add cushioning and a sturdy structure. Is premium feel the point? Glass, metal, or heavy uncoated stock signal quality, but they cost and weigh more. Is sustainability core to the brand? Biodegradable or recyclable materials say so. Then weigh all of it against shipping: because free shipping is expected, a heavier material can quietly eat your margin, so pick the lightest option that still protects and sells.
Layer and material work together
In practice you choose both at once: a glass primary bottle, a paperboard secondary carton, a corrugated tertiary case. The material fits each layer's job, protection and info at the primary, appeal at the secondary, toughness at the tertiary. How you combine them into something that sells is the work of packaging design.
The short version
Packaging types come by layer (primary, secondary, tertiary) and by material (cardboard, plastic, metal, glass, biodegradable). Choose the layer structure your product needs and the material that fits each layer's job and your shipping budget. Start with what is packaging for the overview.

Frequently asked questions
- What are the different types of packaging?
- Two ways to slice it. By layer: primary (touches the product), secondary (groups and presents it), and tertiary (bulk transport). By material: cardboard and paper, plastic, metal, glass, and biodegradable options. A finished product usually combines a layer structure with the right material for each layer's job.
- What packaging material should I choose?
- Match the material to the job. Cardboard and paper are cost-effective and recyclable for general retail and light goods. Plastic is durable and a good moisture and leak barrier, and it's light to ship. Metal protects from light and air but adds weight. Glass feels premium but is fragile and heavy. Biodegradable suits eco-focused brands but may need extra cushioning.
- What is primary, secondary, and tertiary packaging?
- Primary packaging directly contains the product (a bottle, a pouch, the box it sits in) and carries the key info. Secondary packaging groups or presents primary packs (a printed carton, a six-pack) and adds shelf appeal. Tertiary packaging protects products in bulk during transit (shipping cases, pallets, stretch wrap).
- How does packaging material affect cost and shipping?
- Material sets both the per-unit price and the weight, and weight drives shipping. Glass and metal are heavier and cost more to ship; cardboard and plastic are lighter and cheaper. Since free shipping is expected, a heavier material can erase margin, so weigh protection and premium feel against the shipping bill.
