Do you know the purpose of the three main types of packaging used in shipping palletized goods?Â
Understanding the difference between primary, secondary, and tertiary packaging and their applications will help you plan and forecast operational costs in manufacturing and shipping.Â
As a manufacturer of quality stretch wraps for food and plastic pallet wrapping applications, MMP helps protect your products from damage when entering the supply chain and enables you to manage sustainable operations. This guide explores packaging’s diverse roles within a supply chain. The three main types of packaging are:

1. Primary Packaging
Primary packaging is the initial packaging of the product itself. The packaging is added first, then removed last. Primary packaging may include glass, cardboard, flexible plastic pouches and metal cans. For many products, the primary packaging consists of clear stretch plastic that allows consumers to see and closely examine the product.Â
This plastic packaging is typically thin and pliable. It aims to protect the product from dirt, dust and moisture encountered when shipped and handled. It may also have branding, bar codes and shipping instructions printed on it.Â
It serves as a barrier protecting the product's hygienic properties and may be an element of regulatory compliance in the logistics supply chain.Â
Some examples of primary packaging include:
Cereal boxes
Milk cartons
Plastic bottles of liquids
Aluminum cans
Paper bags of charcoal
Plastic bags of flour or rice
Blister packs of pharmaceuticals and small items
2. Secondary PackagingÂ
Secondary packaging consists of packaging used to create unit loads of products. Multi-count boxes holding a specific number of products are an example of secondary packaging designed to make taking inventory quicker and easier. Sacks of rice bundled together with plastic wrap are another example. Secondary packaging:
Provides an added layer of protection
Cuts down on repetitive movements in handling that can slow down operationsÂ
Decreases the risk of damage to individual products
Secondary packaging helps reduce the number of packages that must be handled individually in the manufacturing facility before shipping and adds another layer of protection to the products. Examples of secondary packaging include:
Shrink-wrapped cases of soft drinks or water
Bundled bales of retail floor-ready displays
Multi-count boxes of smaller-boxed products
Cardboard-boxed cases of wine
This packaging may also have regulatory compliance standards it must meet to be used in the supply chain.Â
3. Tertiary Packaging
Tertiary packaging is typically the last to be added and the first to be removed once the products have reached their destination. It's added before shipping from the manufacturing facility to distribution points like retail stores.Â
This type of packaging is typically thick and durable but provides stretch characteristics that help to make tight, stable, palletized loads that can withstand the rough treatment of being shuttled from warehouse to truck several times during the trip to their final destination.Â
The features of tertiary packaging include:
Used in bulk handling, transportation, and warehouse storage for durability and protection.
Prevents damage during shipping and makes palletization more efficient
Some examples of tertiary packaging include:
Pallet stretch wrap
Slip sheets
industrial-size boxes and crates
Steel strapping around baled productsÂ
Understanding the Role of Each Packaging Type
Each of these layers of primary, secondary and tertiary packaging has a role that can improve the efficiency and sustainability of supply chain operations.Â
While secondary packaging was rarely used in consumer-facing options, that’s begun to change as stores and hypermarkets offering discounts on products bought in bulk have become popular.Â
Due to its popularity, brands are focusing more on secondary packaging and branding. In turn, tertiary packaging has to offer added protection from exterior dirt, dust, and moisture elements to preserve the consumer-facing integrity of the new role of secondary packaging.
