16 Packaging Materials and How to Use Them
Packaging your products requires you to have the best possible materials to ensure your product is well-protected and can be transported safely in the best way possible. You also want to make sure that the packaging meets the expectations of your end consumers and delivers on your brand image.
However, with so many different packaging materials out there, it can be daunting to choose a packaging solution that meets all your criteria. In this article, we’ll help you understand common packaging materials and what applications they are best for, along with guidance on how to go about choosing the right packaging materials for your business.
What are Packaging Materials?
To begin, let’s define what a packaging material is. Packaging materials refer to the various components employed in the process of packaging products, including the containers used for product distribution, the materials utilized for transportation, and the external packaging used during shipping. Examples of packaging materials include plastics, metals, cardboard boxes, bio-plastics, and paper. Determining the optimal combination of materials for your products and packages is a crucial task that must be undertaken for each product you sell.
Why is Choosing the Right Packaging Materials Important?
Selecting the right type of packaging is vital to your business operations. It's important to carefully consider your options and use effective strategies when deciding which packaging materials to proceed with. Let’s explore a few key reasons why you should make a careful and informed choice when it comes to choosing what packaging materials you should use.
Product Protection
The first reason is the protection of your products. Every time a product is damaged in transport or even after purchase, it will cost your business financially. It’s important that you utilize a material that is designed to protect the items you sell and help them stay secure through the many locations they’ll pass through during their journey through the supply chain, from shipments to storage and to the consumer's home, you’ll want to ensure that your product is well-protected.
Cost-Effectiveness
Selecting a material that is cost-effective is a great option. You certainly don’t want to spend more on packaging than the return you expect from your product. While some packaging materials might look nice, if they won’t provide a cost benefit to your business, it ultimately may not be the best solution for your product packaging needs.
Sustainability
Sustainability plays a very important role in the world today. More and more businesses are focusing on their carbon footprint and impact on the environment. By picking sustainable packaging materials that are reusable, recyclable, or biodegradable, you can have a positive impact on the environment and improve your company’s reputation. Whether you’re looking for eco-friendly options for food packaging or just looking for more information to begin your transition to more sustainable packaging for your particular industry, we are here to help you on the path to sustainability.
Regulatory Compliance
Certain industries have specific regulations regarding the shipment of materials. For example, some of these regulations ensure the safe handling of particular chemicals or volatile products by requiring them to be stored in specific containers. Creating a quality control checklist and complying with regulations is crucial for the success of your business, making proper packaging even more important.
Brand Image
Finally, it is essential to consider your brand image when selecting packaging materials. Since the packaging will be seen by end consumers for retail products, it should align with your brand's overall vision. For instance, if you specialize in luxury beauty products, it is important to avoid choosing packaging that appears inexpensive, as it could potentially discourage your customers from making a purchase. Ease of use or access to the product is also an important consideration that is determined by the packaging’s compatibility and can contribute to your brand reputation.
How to Choose the Right Packaging Materials
Picking the right packaging materials first requires a thorough understanding of your products. What containers are most compatible with your product? What type of product are you selling, and how should it be contained?
You also want to consider the transportation and shipping of the product. What type of packaging is going to be most cost-effective while still helping the product reach the end goal safely and securely? Finally, consider how it will be displayed in stores for the end consumer. What will look best and feel most authentic to your brand on the shelf?

Best Practices for Packaging Materials
Now that you are a little more familiar with the different types of packaging materials that you could consider using for your products, let’s discuss some best practices for packaging to keep in mind when identifying the best packaging to accommodate your product’s needs.
Evaluate Your Product
The first best practice is to carefully evaluate your product. What is it exactly that you are selling? How does a consumer expect the product to be presented on the shelf? For example, you wouldn't want salsa from a flexible plastic bag or eye cream from a cardboard box. Understanding the ingredients that make up your product packaging is an essential step in finding what works best for your product. As you’re probably aware, there are many types of plastic available on the market. It would be beneficial to familiarize yourself with the different types of resins used in new products to identify compatibility with your product’s ingredients.
Optimize Your Packaging Design
In addition to the material you choose, you also need to think about the design of the packaging you pick. What will draw the consumer’s attention to your product, what messaging can you display on the packaging, and how can you use your packaging for brand marketing?
Utilize the Right Testing and Certification
You should always test your packaging and ensure that you are making the right choice before finalizing an order. You can even get certifications for your product packaging to make sure that it protects your products safely which is especially important for hazardous products.
Streamline Your Supply Chain
