The B1281WH is a 1 oz white LDPE plastic cylinder round bottle with 20-410 neck finish. Cylinder bottles have sharp square shoulders and a square base. Low density polyethylene (LDPE) is marked with the resin identification code of 4. LDPE has high tensile strength and low density. This makes it very tough and "squeezable." LDPE has medium clarity, good chemical resistance, high impact resistance, and high scratch resistance. This item has a 20-410 neck finish. The first number refers to the diameter (in mm), and the second refers to the closure depth, style and thread. This container can be paired with a closure with a matching finish. This container is an opaque white, and well-suited for products with contents that don't need to be displayed. This white container is an excellent canvas for a label or print.
