White Block Zip Bag Buying Guide
Learn how write-on zipper bags simplify product identification and how to select the right size and thickness for your packaging operation.
What are white block zip bags?
White block zip bags are clear reclosable bags with an opaque writing panel printed on the front. The panel provides a visible place to record product information while the clear portion of the bag allows the contents to remain easy to identify.
What information can I write on the white block?
The write-on area can be used to record information such as:
- Part numbers and product names
- Quantities, weights, and measurements
- Lot numbers and production dates
- Expiration or use-by dates
- Assembly, handling, or storage instructions
- Employee, department, or order information
The white panel accepts common writing tools, including pens, pencils, and permanent markers.
What are write-on zip bags commonly used for?
White block zipper bags are used across manufacturing, food service, healthcare, retail, fulfillment, maintenance, and warehouse operations. Common applications include packaging hardware, replacement parts, food portions, samples, kits, medical supplies, craft materials, jewelry, and inventory components.
Which bag thickness should I choose?
- 2 mil bags: A practical choice for lightweight products, food portions, samples, and general organization.
- 4 mil bags: Provide added strength for hardware, parts, tools, kits, and products requiring more handling protection.
- 6 mil bags: Offer heavy-duty protection for heavier, sharper, or more demanding industrial applications.
Are white block zip bags approved for food contact?
The polyethylene bags in this category are made from FDA and USDA-approved polyethylene for food-contact packaging. Select the appropriate size and thickness based on the food product, storage conditions, and handling requirements.
How do white block bags compare with other zip bags?
Choose white block bags when information needs to be written directly on the package. If a writing panel is unnecessary, explore our clear zip bags. For faster machine-assisted or high-volume filling, consider pre-opened zip bags. If easier manual opening is the priority, compare our slider zip bags.
Need a Different Bag Specification?
If you need another size, thickness, material, quantity, closure, or printed bag, tell our packaging team about your product and application requirements.
