Sustainable packaging refers to minimizing the environmental impact of packaging while ensuring product quality and market demand, and achieving optimal use of resources throughout the packaging life cycle. As environmental awareness increases, brands are increasingly looking for sustainable packaging solutions. Understanding and using environmentally friendly materials is essential to meet market demand and promote a greener future for brands. So what exactly is sustainable packaging? This blog post will explore common sustainable materials used in flexible packaging.
1. Biodegradable plastics
Biodegradable plastics are designed to decompose faster than traditional plastics, reducing environmental impact.
| PLA (polylactic acid) | Made from renewable resources such as corn starch, PLA is suitable for various applications, including food packaging. |
| PHA (polyhydroxyalkanoate) | Produced by microorganisms, PHA has excellent biodegradability and is suitable for contact with food. |
| PBAT (polybutylene adipate terephthalate) | PBAT is often blended with other biodegradable plastics to enhance flexibility and durability, making it suitable for a variety of applications while maintaining biodegradability. |
2. Recycled materials
Using recycled materials helps reduce waste and the need for virgin resources.
Common Types
Recycled PET (rPET) or HDPE: Recycled PET or HDPE plastics are widely used to produce flexible bags and films, helping to close the recycling loop.
Recycled Paper: Recycled paper is ideal for applications such as bags and cartons, and can reduce deforestation.
Post-Consumer Recycled (PCR) Plastics: These plastics come from waste plastic products, helping to complete the recycling loop.
3. Plant-Based Materials
Plant-based materials come from renewable resources and are a sustainable alternative to petroleum-based products.
Examples
Paper: Paper comes from sustainably managed forests and is recyclable and biodegradable.
Bio-Based Films: These films are made from sources such as sugarcane or corn, such as sugarcane bio-polyethylene (PE), which can be recycled like traditional PE.
Compostable packaging is divided into industrial compostable packaging and home compostable packaging, which can be broken down in industrial composting facilities or home composting systems, contributing to soil health.
| Compostable Films | Cellulose film | PBS (polybutylene succinate) |
| These films are usually made from PLA or other biopolymers and are suitable for food packaging and other applications. | Cellulose film is derived from wood pulp, is compostable, and has excellent barrier properties. | PBS is a biodegradable and compostable polymer with good thermal and mechanical properties, making it suitable for flexible packaging applications. |
5. Innovative alternatives
Emerging technologies are leading the development of new sustainable packaging solutions.
Mushroom packaging: This biodegradable material is made from mycelium and is an excellent alternative to polystyrene foam.
Seaweed packaging: Edible and biodegradable seaweed packaging is becoming increasingly popular in the food industry.
With the continuous development of various industries, sustainable packaging materials are still being developed and innovated, and more new sustainable packaging materials will appear in the future. The use of sustainable materials can not only enhance brand reputation, but also play a vital role in reducing the impact of packaging on the environment. For brands seeking sustainable packaging solutions, please consider working with packaging suppliers that prioritize environmentally friendly materials, such as BioPack. BioPack provides a variety of packaging solutions with sustainable materials that meet environmental certification standards to meet the needs of different brands and markets.
