White Block Reclosable Bags

White Block Reclosable Bag Types & Thicknesses

Every white block bag in this collection is a single track zipper reclosable bag with a printed white writing block on the front. They are grouped by film thickness, measured in mils, so you can match the gauge to the weight and edge profile of what you are storing:

• 2 mil white block reclosable bags — the economical, high-volume choice for organizing lighter contents such as beads, fasteners, jewelry findings, electronic components, samples and craft supplies. Browse the full size run of 2 mil white block poly reclosable bags.
• 4 mil white block reclosable bags — a stronger, thicker film for heavier, bulkier or sharper-edged items that demand extra puncture resistance. See the complete selection of 4 mil white block reclosable poly bags.

Both gauges share the same labeling advantage and the same secure single track zipper. The 2 mil film keeps cost per bag low for high-turnover packing lines, while the 4 mil film adds durability when contents are weighty or will be handled and reopened many times.

Material & Mil Guidance

These bags are made of virgin polyethylene film that meets FDA and USDA requirements, so they are suitable for food and pharmaceutical packaging in addition to general industrial use. Virgin resin produces a consistent, clean film without the contaminants found in recycled blends, which matters when the bag will touch food, supplements or medical items. Choosing a mil is a balance between cost and protection. Reach for 2 mil when contents are light and you are packing in volume and want the lowest price per bag. Step up to 4 mil when items are heavier, have sharp corners, or the bag will be opened and resealed repeatedly. Because each bag also carries a printed white writing block, you keep the labeling benefit at whichever thickness you pick.

Use-Cases by Industry

The write-on white block makes these reclosable bags a fit across many sectors:

• Hardware & manufacturing — kit small parts, screws, washers and components and mark each bag with its part or job number.
• Medical, dental & pharmacy — bag supplies, samples and unit-dose items and note patient, lot or expiry information directly on the bag.
• Jewelry & crafts — sort beads, charms and findings by type and write the style or color on the panel.
• Retail, e-commerce & fulfillment — organize SKUs, returns and backstock with hand-written identifiers, keeping contents clean and moisture free.
• Labs & field service — label specimens, parts and collected items on the spot without carrying a label printer.

How to Choose the Right White Block Bag

Start by measuring your item flat and adding clearance so it slides in and the zipper still closes easily; the listed dimensions are width by length. Next, judge the weight and edges of your contents to decide between 2 mil and 4 mil. Then confirm you want the printed writing panel for labeling rather than a plain clear bag. If your exact dimensions are not stocked, Arplast offers custom sizes and custom printing on request, so you can have the white block bag built to your specifications or add your own logo and instructions. If you do not need the write-on panel, the clear reclosable poly bags offer the same single track zipper closure in a fully transparent film, and the broader reclosable bags category covers every zip top style we manufacture.
