The Procedure for Separating Plastic Grocery Bags

  • Clap technique

The clap technique does not need finger-licking, although it might be challenging to perfect. 

Thumb and index finger on bag’s top corner. It should be 2 or 3 inches from your palm to a bowl.

Now clap twice or three times. It will drive air into the bag, allowing that corner to open. Grip the open edge and shake or blow it to empty the bag.

  • Pinch and rub 

It is the simplest way and the suggested one. The most significant thing is that you can do it with only one hand. So you may open the bag without having to set down those lovely apples you chose. 

Grab the bag’s top with your thumb and finger. Rub your hands together in opposing directions or tight circles. The friction will cause the bag to split from itself. It is quiet and can be done with one hand.

Hold the bag’s closure between your index and middle fingers. Pull it tight and secure it between your ring and pinky fingers. 

You may separate them by rubbing the opening two or three times. Open the bag or blow or shake it vigorously to separate it and completely open it.

Why Do Plastic Bags Adhere to One Another?

Static electricity causes plastic bags to stay together. They will attract when they take up opposing charges. More precisely, and most likely, the bags are sticking together due to Van der Waals’s force.

Static electricity is straightforward. Things can take up a little electrical charge by rubbing against another surface, and if opposing directions are picked up, they will attract. It does not seem a very plausible reason for comparable bits of plastic to cling together since they’d generally pick up the same charge signal and repel. 

If the plastic somehow took up patches of a positive and negative charge, oppositely charged patches would locate each other and stay together. One technique to check whether this impact is significant is to purchase a small hand-held piezo-electric ion pistol and see if spritzing ions at the plastic significantly changes stickiness.
