“Before you change the world, go around your house three times.” (Chinese proverb) Green Homes is an initiative aimed at people concerned about the environmental and social impact of their daily decisions and habits that promotes self-control in domestic water and energy consumption, proposes measures and saving behaviors and encourages a more ethical and environmentally friendly purchase.
As an extension of the previous post, here are some characteristics of the seven main types of plastics commonly used in containers and packaging and some extra tips to reduce the amount of plastics we use.
Type 7: Others. It is advisable to avoid using the plastics included in this family because we do not know exactly what type of plastic it is, and it can even be harmful to health, especially if it is in contact with food products. Another compelling reason not to use this type of plastic is that they are often difficult to recycle, and these plastic products are finally disposed of by incineration, releasing harmful compounds into the atmosphere. This type of plastic appears in the trays that resemble corkopan that contain meat, fish, pies…
Polypropylene is very similar to polyethylene, but has a higher heat resistance, which is why it is often used for food packaging and food storage bags and containers.
Polypropylene can even withstand twisting movements of up to 360 degrees without breaking and is therefore very difficult to break. Its production cost is relatively low and simple, and it is available in many countries and communities.
Its high resistance to chemicals and fatigue adds to its durability and versatility as a packaging material and option for bottle hinges and caps attached to the main bottle by a thin layer of plastic.
It offers great color versatility, as it can be produced as an opaque or transparent thermoplastic and used when some light transfer is desired. Its lower density allows it to be used in applications where weight savings must be a key consideration.
Polypropylene is impermeable and extremely resistant to moisture absorption, which adds to its advantages and flexibility as a packaging material. Its semi-crystalline nature also offers high flexural strength, making it resistant to general wear and tear and ideal for items that must undergo higher levels of physical stress. It is also resistant to mold, rot and bacteria.
What plastic is used for
CONSERVATION ACTION The problem of plastic pollution is very serious and further study is urgently needed. It also requires immediate action such as:- Reduction of the use of plastic as packaging, which is normally discarded immediately. Re-use of plastics should be promoted. – Plastic packages and bags should display a warning about the dangers of plastic pollution and the consumer should be encouraged to use their own bags and recycled paper bags.
Physical properties of plastic
We will continue to report from this blog about the types of plastic containers commonly used in the packaging industry, which have become a common part of everyone’s life and are often used to wrap, store or protect many of the products and foods that are around us.
It is used for bottles, trays, bags and certain wrappings. It is easily recycled and has some varieties such as CPET, which serves, among other things, as packaging for ready meals. As it is partially crystallized, it withstands high temperatures and is ideal for heating in all types of ovens, including microwave ovens. APET or amorphous polyethylene terephthalate, which is impact resistant, is also a barrier against oxygen, water, carbon dioxide and nitrogen. Carbon dioxide and nitrogen.
It has a variety of formats such as bottles, caps, serves as a sealant for trays and forms a thin film for bags and wrappers. One variety is HDPE, which is used especially for packaging milk in bottles and is easily recycled and does not contain toxins.
