1.What is Primary VS Secondary Packaging?

Primary Packaging - Sourced: OPC Direct

Based on this name, maybe you should know its definition, right. Primary packaging refers to the first packaging of a product when it is taken off the production line. This form of packaging will ultimately be marketed to consumers, so it must meet their aesthetic preferences. It comes into direct contact with the product, thus protecting it from the effects of air and temperature.

Secondary Packaging - Sourced: Contract Pharma

Secondary packaging refers to the packaging of one or more primary packaging. It is convenient for product transportation and storage. Therefore, it ensures that the products are not damaged or stolen during logistics, warehousing, and retail processes. Besides, some secondary packaging also can be designed to enhance the appearance of the product.

2.What is the Benefits of Primary VS Secondary Packaging?

Primary vs secondary packaging is inevitable for every product, and the forms of packaging are becoming increasingly diverse.

(1)Benefits of primary packaging

Extending product shelf life

The product will become damp and deteriorate after prolonged exposure to air and water vapor. Primary packaging can protect products from the effects of air, light, and humidity can extend the shelf life of products.

Ensuring product hygiene

If the product is exposed to the outside for a long time, it will be affected by dust, microorganisms, etc. Primary packaging can block the product from being affected by external bacteria or other harmful substances.

(2)The benefits of secondary packaging

Addingvalue to the product

To tell the truth, packaging is required in any industry. Let’s take a look at which industries primary vs secondary packaging are specifically applied to!

(1)Personal care industry

Personal Care Industry - Sourced: Environmental Factor

The products in the personal care industry are daily necessities with high sales volume, and most of them require packaging. For example, the facial cleansers, shampoos, shower gels, etc. that we usually use need to be packaged.

(2)Food industry

Food Industry - Sourced: ProAmpac

Both beverages and snacks require packaging. For example, beverages generally require plastic bottles and other primary packaging, followed by secondary packaging using shrink wrap to facilitate the handling and transportation of beverages. These packaging materials not only need to ensure the freshness and hygiene safety of the food, but also need to be aesthetically pleasing and leave a good first impression on consumers.

(3)Pharmaceutical industry

Pharmaceutical Industry - Sourced: OpenSecrets

Liquid drugs need to be packaged once in glass or plastic bottles, and there should be a certain choice of color and material for the bottles. In addition, secondary packaging such as paper boxes will be used for liquid drugs.

The medicine has higher requirements for packaging materials. Drug packaging materials need to have characteristics such as moisture resistance, light resistance, and oxidation resistance to ensure the safety.

5.Primary VS Secondary Packaging: What Are Their Difference?

Believe it or not, there are several differences between primary vs secondary packaging? Let’s take a look together.

Primary VS Secondary Packaging - Sourced: Designertable

(1)Contact with the product

Both packaging forms serve to protect the product. The primary packaging comes into direct contact with the product, while the secondary packaging does not need to come into direct contact with the product.

(2)Capacity

Generally speaking, the capacity of secondary packaging is greater than that of primary one. Secondary packaging can accommodate one or more primary packaging.

(3)Function

Function - Habefast

These two packaging forms are devised in function. Primary packaging can directly protect the product. In addition, to attract customers’ eyes, direct interaction with customers is also possible. While, secondary packaging focuses on grouping. It provides additional protection for the product and facilitates marketing efforts.

(4)Cost

Due to the need for direct contact with the product, the primary packaging requires the use of special materials, resulting in higher costs. The use of secondary packaging in large quantities results in relatively low costs.

(5)Material

Material - Sourced: Tangent Materials

The two packaging forms are different in materials. Due to features of primary packaging, the materials need to be compatible with the product, including materials such as plastic and glass. And the materials for secondary packaging often include cardboard, plastic, wood, etc.

(6)Use cases

They are used in different cases. Primary packaging is mainly used to display products on cargo racks to attract customers’ attention, while secondary packaging is mainly used during transportation and handling processes.

(7)Overlap

To be honest, there is a overlap of the two packaging forms at some level. For example, the beverages we purchase from product shelves come with both primary and secondary packaging.

6.What Quality Control and Testing for Primary VS Secondary Packaging?

To protect the product and maintain its shelf life. Primary vs secondary packaging needs to be inspected before it can be used normally.

Quality Control and Testing - Sourced: Extended Web AppTech

(1)Quality control and testing for primary packaging

Compatibility testing

Whether the product is compatible with packaging materials is a question that needs to be considered. Once incompatible, some chemical reactions may occur, affecting the quality of the product.

Sealing integrity test

The product may deteriorate if exposed to air and sunlight for a long time. Therefore, it is very important to check the sealing integrity of the packaging. For example, it is necessary to check whether the bottle cap is tightened and whether the packaging of the bag is sealed tightly.

(2)Quality control and testing for secondary packaging

Checking label and printing quality

The product label includes model, production date, brand, barcode, etc., which facilitates product identification and tracking. Therefore, you need to check whether the product label is accurate, the quality of printing, and whether it is easy to fall off.

Transportation testing

Secondary packaging is mainly used for transportation, storage, etc. Expose the packaging to various environments to test its stability. Simulate the impact and vibration of the packaging during transportation to test whether the packaging can protect the product.

7.What Are the Common Machines for Producing Primary VS Secondary Packaging?

For different types of packaging, there will be different machines. Do you know which ones are used for primary packaging and which ones are used for secondary packaging?

8.How to Determine Primary VS Secondary Packaging for Products?

When choosing primary vs secondary packaging for a product, it is not a blind selection, but rather a comprehensive consideration of some factors.

(1)Product type

Why do some drugs need to be packaged in glass bottles while others need to be packaged in plastic bottles? The product type will determine the type of packaging. For example, some drugs can decompose and spoil when exposed to light, so brown glass bottles are needed for packaging.

(2)Cost

Some products can be packaged in multiple ways, such as laundry detergent which can be packaged in bags or bottles. If you produce a large quantity of products that require bulk transportation, you need to consider transportation costs.

(3)Sustainability
