Apart from the knowledge of many, plastic bags pose a serious worldwide problem. They are considered one of the many pollutants of the earth. So to minimize the threat, many campaigns have been established banning the production and use of plastic bags.
However, we cannot deny the benefits we can get from plastic bags. They are very light which make handling of any things easier. They are very economical as they cost only a cent per piece. They are strong and durable in which they can hold even heavy and massive materials. And they are multipurpose wherein you can do so much in one plastic. Yet still problems arise because plastic bags are not so friendly for the environment. It takes years for them to decompose and all they leave are litters everywhere.
Finally, the bags are recyclable. When you buy something that comes packed in a resealable nasty bag you are actually getting something useful, besides the product that you are buying. Recycling these bags again and again also helps in that there are less nasty bags and appearance littering the planet. Resealable plastic bags are great for keeping items safe. Many items can be broken from drinking water leaks or from having something built on them, which is why being able to fully close off the bag that products is in has intended that items are no longer in risk of damage from drinking water or wetness during transportation, while in the shop and soon after they have been sold.
