Size and Specifications

This is the most crucial specification, directly determining a bag's capacity. These include:
1. Width: This refers to the horizontal dimension of the bag's opening, typically ranging from 2 inches (approximately 5cm) to 40 inches (approximately 100cm). For example:
Small: 2 inches, 4 inches (suitable for small parts, jewelry, etc.)
Medium: 6 inches, 8 inches, 12 inches (suitable for food, stationery, small electronic components)
Large: 16 inches, 24 inches, 36 inches (suitable for clothing, large parts, and bulk goods)
2. Length: This refers to the vertical dimension of the bag from the opening to the bottom seal. It is typically designed in conjunction with the width, ranging from 3 inches (approximately 7.5cm) to 60 inches (approximately 150cm). For example, an 8-inch-wide bag might have a 10-inch, 12-inch, or other length. 3. Opening size: The width of the pre-opening is usually slightly smaller than the overall width of the bag (to avoid damage caused by excessive opening), generally 70%-90% of the bag width.

 

Application notes
 

 

When choosing a material, you can consider the following factors:
 

Protection needs: If you want to provide a higher level of protection for your card, you can choose a thicker material, such as PET. If you just want to protect the card from basic scratches and damage, PVC or PP may be enough.
Budget: Card holders of different materials have different prices. PVC card holders are usually the most affordable option, while PET card holders can be more expensive. Choose the appropriate material based on your budget.
Environmental awareness: If you have certain environmental concerns, you can choose chlorine-free materials such as PP or PET, as they are considered to be more environmentally friendly options than PVC.
