Plastic wrap, known as cling-film in the United Kingdom, is a thin polymer material, roughly 0.0005" (12.7μm) thick, typically used for sealing food items in containers to keep them fresh. The wrap, typically sold on rolls in boxes with a cutting edge, clings to many smooth surfaces and can thus remain tight over the opening of a container with no adhesive or other devices. Some find it difficult to use, as it both clings and tears easily. A polymer is a generic term used to describe a substantially long molecule. ... Fresh (1994) is the debut film of writer and director Boaz Yakin. ... An adhesive is a compound that adheres or bonds two items together. ...

Plastic wrap was first made from PVC, which remains the most common material, but non-PVC alternatives are now being sold because of concerns about the transfer of plasticizers from PVC into food. PVC is still used because of its permeability to water vapor and oxygen, which makes it suitable for preserving meat. Polyvinyl chloride (PVC) is a widely-used plastic. ... Plasticizers are additives that softens a material (usually a plastic or a concrete mix) they are added to. ... Water vapor condensing over a cup of hot tea Water vapor or water vapour, also aqueous vapour, is the gas phase of water. ...

To use plastic wrap effectively for sealing containers, tear off a section and touch one side of the wrap to one side of the container near the opening, allowing the wrap to cling there and make as smooth a seal as possible. Then, stretch the plastic wrap over the opening and touch the other end of the wrap to the opposite side of the container. Finally, pull the remaining sides of the wrap over the remaining edges of the opening, and flatten the wrap against the edges around the opening as completely as possible. This may take some experimenting and practice to master. Containers in the port of Kotka (Finland) on the Baltic Sea. ...

Note that plastic wrap does not tend to cling to other plastics, but it will cling to itself quite easily. Plastic bottles for recycling Plastic is a term that covers a range of synthetic or semisynthetic polymerization products. ...

Commonly known brands of plastic wrap include Saran wrap and Stretch-Tite. A similar material can also be made at home by spreading clear glue on a smooth flat surface and allowing it to dry. Depending on the thickness of the layer of glue, it may tear easily, or it may be tougher and more difficult to stretch. Saran is the trade name for a number of polymers made from vinylidene chloride (especially polyvinylidene chloride or PVDC), along with other monomers. ... Historically, glue only refers to protein colloid adhesives prepared from animal tissues, such as hide glue, bone glue, or fish glue. ...
