Regarding packaging, there are various options for manufacturers and retailers. The most environmentally friendly packaging can vary depending on the type of product being packaged. There are several different types of packaging, each with its own advantages and disadvantages. Some may be better suited for certain types of products than others. Environmental research institutions have identified four main types of packaging: paper, card, bottle, and pouch. Each category has many subcategories such as inner or outer seals.

Paper packaging

Paper packaging is made from wood pulp or other vegetable-based substances. Some may even be made from sustainable sources. Paper packaging is not recyclable, biodegradable, or compostable. Paper containers are made to hold liquids from paper, plastic, or polyethylene. Paper packaging is usually colored and lined with polyethylene or polypropylene to increase its durability and impart opacity.

Card packaging

Card packaging is made from paper and most likely recycled. Card packaging is usually transparent and colored.

Bottle packaging

The bottle packaging is made from a polyethylene or polypropylene blend. This type of packaging is usually clear.

Sealable pouch packaging

Sealable pouch packaging uses a polyethylene or polypropylene blend and is often black in color.

In sealable bagging

In sealable bagging is constructed from polyethylene or polypropylene and is often black.

Flexible pouching together with bagged ice or dry ice

Flexible pouching is often combined with the process of freeze-drying, where ice or dry ice is placed in a pouch and then heated to destroy any microorganisms that may be present.

結論

Paper, card, bottle, sealable bags, and pouch packaging all have their advantages and disadvantages. When choosing the most environmentally friendly packaging type, it is important to consider the type of product being packaged. For example, if a manufacturer of a food product is considering paper, card, or bottle packaging, they would want to ensure that their product would be safe and able to be stored and transported without being damaged. The environmental factors to look at would be the amount of energy needed to produce the packaging, the amount of time that it would take to recycle the packaging, and if the packaging would be safe for the products being stored in it.
