Packaging bags can have various types of zippers, depending on their design and intended use. Some common types of zippers used on packaging bags include:
Standard Zipper/Ziplock Zipper:
They work by pressing the two interlocking plastic strips together to seal the bag and pulling them apart to open it. They are used in a wide range of packaging, including food storage bags.
Tear-Notch Zipper:
These zippers are designed with a tear-notch feature that allows users to easily tear open the sealed bag when they want to access the contents. They are often used for single-use packaging.
Slider Zipper:
Slider zippers have a larger pull-tab or slider mechanism that makes them easy to open and close. They are often used on resealable bags for food, snacks, and other consumer products.
Child-Resistant Zipper:
These zippers are designed to be difficult for young children to open. They often require a specific combination of actions, such as pressing and sliding, to open, making them suitable for packaging products that need child-resistant closures.

A pinch and slide zipper is a type of zipper used on packaging bags that requires users to pinch the sides of the zipper together and then slide their fingers across it to seal or open the bag. This design is typically seen in resealable bags and is known for its simplicity and ease of use. Users can seal the bag by pinching the two sides of the zipper track together, creating a secure closure. To open the bag, they slide their fingers along the zipper track, separating the interlocking components. It's a user-friendly and effective way to provide resealable functionality in packaging, commonly used for food storage bags and other similar applications.This kind of zipper usually works together with frosted stickers. The frosted stickers can increase the friction between the fingers and the bag, making it easier to open the bag.
