Sustainable and environmentally friendly packaging
Today’s consumer market, due to the high volume of production and consumption, leads consumers and producers and all industry owners to green and environmentally friendly design. The activities that manufacturers and owners of brand names do in this field include:
Reducing the amount of garbage
Using products with easy recycling
· Greater amount of recycling
Use of materials with renewable resources
Less use of packaging
Seven principles have been proposed by manufacturers in the field of environmentally friendly packaging production:
· Removal of packaging in some products or food
· Reduction of material packaging
Use of reusable packaging
Use of reusable packaging
Profit (economic profit – the ultimate goal of saving or neutral cost)
Despite many scientific advances, the number of recyclable materials available for product packaging is still limited and the traditional materials used in packaging are important pollutants for the environment in terms of high oxygen consumption and high humidity. Process. However, with better design, more suitable materials and more detailed planning (especially from ECO member countries), environmentally friendly packaging can be achieved as an alternative to the current packaging. Besides that, it should be kept in mind that providing environmentally friendly solutions in the field of sustainable packaging should be in line with maintaining the high quality of the product and its packaging.
Products with a growth cycle of less than one year must be able to be converted into other products, reused or returned to the soil (in composite materials, initially by reducing the amount of water and carbon dioxide and without leaving any residual material within 45 90 days).
Using reusable resources:
Due to the effects of global warming and the reduction of natural resources, it is necessary to look for ways to reduce the amount of use of natural resources, or to make them reusable, or to have the ability to recycle all of their non-renewable components.
High quality plastic packaging:
· HDPE HDPE (high density polyethylene)
· LDPE LDPE (low density polyethylene)
· PET (Polyester)
· RPET RPET (recycled polyester)
· PS PS (polystyrene)
Lower quality plastic packaging:
PVC PVC (vinyl chloride)
· PC (Polycarbonate)
Polycarbonate For example, PLA and some fibers are very fragile and resistant in extreme cold and freezing conditions, and of course significant progress is being made in this field.
Types of sustainable and environmentally friendly plastics:
· Polylactide Acid (PLA) Plastics
· Bagasse – Sugar Cane Pulp
· Palm Fiber
· Biomass Fiber Composite – AgroResin
· Reed Fiber – a Japanese Innovation
· PlasTerra – Biodegradable Plastic
. Polylactide Acid (PLA) Plastics
PLA is a transparent plastic made from natural materials (such as corn starch).
Bagasse (consisting of fibers that have a natural ivory color. When the sugarcane juice is extracted from it, a substance remains, which is bagasse.)
Palm Fiber (It is produced from the remaining materials from palm oil extraction. This material is very similar to bagasse and both of these materials are suitable for producing packaging such as disposable containers.)
Biomass Fiber Composite – AgroResin (it is made of degradable materials and the ability to be fertilized and converted into organic materials for biomass agricultural purposes, and it actually has natural roots and has similar uses to palm fiber in the packaging industry.)
Reed Fiber (fibers derived from reed stems that grow rapidly and dramatically. They can be converted into other organic materials and return to the material recycling cycle. These materials grow in coastal areas and by the seas or riverbeds. These materials had no food value and are produced only for the production of this type of plastic in Japan.)
PlasTerra (a type of degradable plastic that consists of different bioresins with high degradability such as starch, PLA, and other types of fiber.)
Examples of sustainable packaging
1. Using materials with high recycling capability
100% recyclable bottle design
2. Reduction of chemicals and adhesives in the printing industry as well as packaging joints
Labels with high decorative aspects and reduction or elimination of chemicals, especially adhesives
3. Increasing the frequency of using product packaging:
Use of reusable cloth bags as an alternative to nylon bags
4. Using natural elements such as metal as an environmentally friendly material with high recycling capability:
5. Creative packaging with natural materials
Banana leaves have good properties in the food industry, they have a thick fatty surface that stores the fat and moisture of the ingredients well. Also, these leaves are soft and flexible and therefore can be molded in different packaging methods. They can be used to open the packages formed with these leaves easily and with the help of a simple hole.
6. Packaging as a deterrent to environmental pollution
Batteries are one of the most polluting products of human production and the danger that arises from the mixing of these deadly wastes with other urban wastes is very common. Therefore, accuracy in the way of distribution, use and disposal of batteries can be considered very important in the design process of our designers.
