Why is Plastic Packaging Still Widely Used in All Aspects?


Let's start with the conclusion: plastic packaging's unparalleled blend of durability, cost-efficiency, versatility, and protective qualities makes it an indispensable choice across industries, ensuring product safety and consumer convenience while driving innovations in sustainable practices. choice across industries, ensuring product safety and consumer convenience while driving innovations in sustainable practices.


In today's increasingly environmentally sustainable world, we wonder why plastic packaging still dominates our shelves and our lives. From supermarkets to shipping warehouses, the presence of plastic is undeniable, and everything from the freshest strawberry to the latest smartphone is wrapped in plastic packaging.XLD explores the long-term reliance on plastic packaging, and through real-world product examples, we will reveal the reasons for its enduring popularity.

The unrivaled benefits of plastic packaging

Plastic packaging is not ubiquitous without reason. Its benefits span a wide range of durability, cost-effectiveness, and versatility, making it a difficult, if not irreplaceable, material to use in many situations.


1. Durability and protection

Let's think about it, how does a bag of potato chips have to be protected from the factory to your living room in order to keep the crunchy texture going into your mouth? The packaging must withstand the stresses of transportation while maintaining the crunch and texture of the chips. Plastic's exceptional barrier properties to moisture and air prevent spoilage and extend the shelf life of food products, and few materials can achieve this level of efficiency.

2. Cost-effectiveness and efficiency

Plastic offers outstanding advantages in terms of economic production and logistics. It is lightweight and easy to manufacture, so production and transportation costs are low, and consumers benefit from the relatively lower price of the final product. The lightweight nature of plastic packaging (e.g. PET bottles) reduces transportation costs and the associated carbon footprint, suggesting that plastics can also have a positive effect on environmental sustainability.

3. Versatility and design flexibility

The adaptability of plastics allows innovative packaging solutions to be tailored to specific product requirements. For example, for pharmaceuticals, a balance between safety and convenience is essential, as plastic packaging can provide both child-resistant features and easy access for the elderly.

4. Addressing environmental concerns

The conversation around plastics is changing, with more sustainable practices being introduced across the industry. Recycling and the development of biodegradable and bio-based plastics are part of the effort to reduce environmental impact. The recyclability of PET and HDPE plastics, for example, demonstrates the potential of the circular economy to extend the life cycle of plastics through reuse and recycling.

Types of Plastics Used in Packaging

1.         PET (Polyethylene Terephthalate): Widely used for its clarity, strength, and barrier properties. It's commonly recycled.

2.         HDPE (High-Density Polyethylene): Known for its strength and used in packaging that requires a good barrier against moisture and air. It's also commonly recycled.

3.         LDPE (Low-Density Polyethylene): Often used for its flexibility, such as in bags and wraps. Its recyclability can vary by location.

4.         PP (Polypropylene): Has a high melting point, making it suitable for packages that might be exposed to heat. It's recyclable, though less commonly recycled than PET and HDPE.

5.         PVC (Polyvinyl Chloride): Used in various packaging applications but are less commonly recycled due to the presence of additives and the complexity of recycling processes.

6.         Multi-layer Plastics: These are combinations of different plastics (and sometimes materials like aluminum) to achieve specific barrier properties. While excellent for preserving product quality, they are among the most challenging to recycle.

We have categorized these materials in a table to better present you with their pros and cons:

PET (Polyethylene Terephthalate)Clear, strong, lightweight, good barrier properties, widely recyclableCan absorb odors and flavors over timeMedium
HDPE (High-Density Polyethylene)Strong, good moisture and air barrier, widely recyclableNot as clear as PET, can become brittle in cold temperaturesLow to medium
LDPE (Low-Density Polyethylene)Flexible, good for bags and wraps, varying recyclabilityLower barrier properties than other plastics, recycling facilities may not accept itLow

PP (Polypropylene)

High melting point, good for hot fill products, recyclableCan be difficult to recycle due to lack of collection facilitiesMedium
PVC (Polyvinyl Chloride)Versatile, can be used for both rigid and Flexible packaging, less commonly recycledContains chlorine which can release harmful chemicals, difficult to recycleLow to medium
Multi-layer PlasticsExcellent barrier properties, suitable for a wide range of products, challenging to recycleComplexity of separating layers makes recycling difficult, often not recycledHigh

Plastic packaging in everyday life

To further illustrate the advantages of plastic packaging, let's take a look at its applications in different industries:

Food and beverages: Thanks to the ability of plastics to maintain product freshness, fresh salads in sealed plastic containers arrive at consumers crisp and flavorful. The resealability of many plastic packages, such as coffee or dried fruit packages, offers consumers the added convenience of preserving the taste and quality of the product over time.

Healthcare: Sterility is critical for healthcare products, and plastic packaging excels in this area. For example, syringes are packaged in plastic to ensure sterility before use. This not only safeguards the health of the patient, but also extends the shelf life and accessibility of essential medical supplies.


The continued prevalence of plastic packaging is a testament to its unrivaled utility in a variety of industries. While the environmental impact of plastic packaging cannot be ignored, the continued advancement of recycling technology and sustainable materials is an encouraging step toward a more balanced coexistence with our planet. As consumers, understanding the dual nature of plastic - its benefits and its challenges - enables us to make more informed choices and support initiatives that promote sustainability without compromising the quality and safety of the products we rely on.
