With the increasing awareness of environmental protection, the blister packaging industry is undergoing a green revolution. The use of environmentally friendly materials to make blister packaging can not only significantly reduce the burden on the environment, but also meet consumers' demand for sustainable products.
1. Types and characteristics of environmentally friendly materials
Degradable materials
- PLA: Made from renewable resources such as corn starch, it is biodegradable and widely used in food packaging and disposable tableware. PLA materials can be completely degraded into carbon dioxide and water under composting conditions, which is harmless to the environment.
- PHA: Produced by microbial fermentation, it is completely biodegradable and suitable for food packaging and medical supplies. PHA materials have good biocompatibility and mechanical properties and can be degraded in the natural environment.
- Starch-based materials: Made from starch such as corn and potatoes, it is biodegradable and used for food packaging and cushioning materials. This material can be completely degraded under certain conditions to reduce plastic waste.
Recyclable materials
- Recycled paper and cardboard: Made by recycling waste paper, it is widely used in packaging boxes, bags, etc., and can be recycled many times to reduce tree felling.
- Recycled plastics: such as rPET, used to make bottles and containers, reducing the use of virgin plastics. rPET materials have good transparency and mechanical properties and can be recycled multiple times.
Reusable materials
- Glass: can be used and recycled multiple times, often used in beverage and food packaging. Glass materials are non-toxic and high temperature resistant, making them an ideal choice for environmentally friendly packaging.
- Metals: such as aluminum and steel, which can be recycled infinitely and used for canned food and beverages. Metal packaging has good barrier properties and mechanical strength and can effectively protect products.
Natural fiber materials
- Bamboo fiber: biodegradable, used for tableware, packaging boxes, etc. Bamboo fiber materials have good strength and toughness, making them an ideal choice for environmentally friendly packaging.
- Sugarcane bagasse: a byproduct of sugar production, used in food containers and packaging boxes. Sugarcane bagasse materials are completely degradable, reducing the impact on the environment.
- Mushroom packaging: made from mycelium and agricultural waste, biodegradable, used for cushioning packaging. Mushroom packaging has good cushioning properties and is suitable for electronic products and fragile items.
Bio-based materials
- Bio-based PE (polyethylene): Made from renewable resources such as sugarcane, it has similar performance to traditional PE, but with a lower carbon footprint. Bio-based PE is widely used in films and packaging bags.
- Bio-based PET: Some of the raw materials come from renewable resources and are used in beverage bottles, etc. Bio-based PET has good transparency and mechanical properties, which can reduce dependence on petroleum resources.
Innovative materials
- Seaweed-based materials: Extracted from seaweed, biodegradable, used in films and packaging bags. Seaweed-based materials have good barrier and biodegradability and are an emerging choice for environmentally friendly packaging.
- Water-soluble materials: such as PVA (polyvinyl alcohol), which dissolves in water and is used for small-dose packaging. Water-soluble materials can be completely dissolved after use and will not produce plastic waste.
- Paper-plastic composite materials: Combine paper and degradable plastics to improve strength and environmental protection, and are used for food packaging. This material has both the recyclability of paper and the waterproofness and strength of plastic.
2. Application of environmentally friendly materials in blister packaging
- Food packaging: Blister packaging made of PLA or bio-based PET can effectively maintain the freshness and hygiene of food while reducing plastic waste. For example, fruit blister boxes made of PLA can be completely degraded under composting conditions, which meets environmental protection requirements.
- Electronic product packaging: Blister packaging made of rPET or bio-based PE can provide good protection and display effects while reducing the impact on the environment. For example, electronic product packaging boxes made of rPET have good transparency and mechanical properties and can be recycled many times.
- Medical supplies packaging: Blister packaging made of PHA or paper-plastic composite materials can ensure the sterility and safety of medical supplies. For example, medical device packaging boxes made of PHA can be completely degraded after use, reducing medical waste.
