Partners Brand PB3988 White Block Reclosable Poly Bags 4x4 4 mil Clear 1000 pack

Partners Brand PB3988 Poly Bags

These clear polyethylene bags measure four inches by four inches and feature a white write-on block for labelling. A reclosable seal keeps contents secure during storage or transit. Each pack contains one thousand bags, making them suitable for high-volume shipping rooms and mailrooms. The four-mil thickness provides tear resistance for small parts and documents.

Practical limits of the reclosable seal

The zip-style closure is designed for repeated opening and closing but is not rated for heavy or sharp objects that could stress the track. Four-mil film resists punctures from light items yet will stretch under concentrated weight. Bags are not intended for vacuum sealing or liquid containment. Users should verify that the four-inch square interior accommodates their specific product dimensions.

The specification that decides fit

The four-inch by four-inch inside dimension is the single measurement that determines whether your items will fit. If components exceed this width or length, a larger bag size is required. The one-thousand-count pack suits operations that process hundreds of parcels daily, while lower-volume users may find the quantity excessive. White block labelling area is sized for handwritten codes or small adhesive labels.
