Roll Specifications
 

Since this is a roll-to-roll design, roll parameters are also key specifications:

1. Quantity per Roll: Depending on the size and thickness of the bags, the number of bags per roll can range from 100 to 1,000 or even more. For example, a small, lightweight bag might have 500-1,000 bags per roll, while a large, thickened bag might only have 50-200 bags per roll.

2. Core Size: The core (the cardboard or plastic tube that supports the bags) is typically 3 inches (7.6cm) or 3.5 inches (8.9cm) in diameter, compatible with the reel size of most automated packaging equipment.

3. Roll Diameter: This is the maximum outer diameter of the bags on the roll. It is affected by the quantity per roll and the thickness of the bags, but is generally between 6-12 inches (15-30cm) for easy storage and loading.

 

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.
