Glad Press'n Seal uses Griptex technology to protect food with a leak proof and airtight seal. Great for storing and protecting leftovers, this multipurpose wrap seals tightly onto a variety of surfaces, such as paper, plastic, metal, wood or other dry surfaces. The Griptex technology activates when pressure is applied and seals to itself, allowing you to create custom shaped food storage bags to freeze food or to make individual portions. It also works well around the house or at work to keep things clean and protected. Press'n Seal wrap is simple to use and easy to handle. The wrap is BPA free and microwave safe. Glad protects and seals with ease. Directions: Pull the plastic food wrap from the roll. Use serrated lid for clean tearing. Place it over the desired area. Press food wrap along dry rim. Glad Press'n Seal wrap's activated gripping texture tightly seals to almost any dry surface. When using in the microwave, allow at least 1 inch of space between wrap and food. Turn back one corner of food wrap to vent. Ingredients: BPA Free Wanings: Avoid contact with cutting edge.
