Shrink wrap

Shrink wrap, also shrink film, is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. Heat can be applied with a handheld heat gun (electric or gas), or the product and film can pass through a heat tunnel on a conveyor.

Composition

The most commonly used shrink wrap is polyolefin. It is available in a variety of thicknesses, clarities, strengths and shrink ratios. The two primary films can be either crosslinked, or non crosslinked. Other shrink films include PVC, Polyethylene, Polypropylene, and several other compositions.

Coextrusions and laminations are available for specific mechanical and barrier properties for shrink wrapping food. For example, five layers might be configuration as EP/EVA/copolyester/EVA/EP, where EP is ethylene-propylene and EVA is ethylene-vinyl acetate copolymer.

Manufacture

A shrink film can be made to shrink in one direction (unidirectional or mono-directional) or in both directions (bidirectional).

List of Dexter episodes

Dexter is an American television drama that was broadcast on the premium cable channel Showtime from October 1, 2006 to September 22, 2013. A total of 96 episodes of Dexter were broadcast over eight seasons. The series is based on characters created by Jeff Lindsay for his "Dexter" series of novels. The series follows the life of Dexter Morgan (Michael C. Hall), a Miami Metro Police Department blood pattern analyst with a double life. While investigating murders in the homicide division, Dexter hunts and kills murderers and criminals who have escaped the justice system. Although the first season is based on the events of Darkly Dreaming Dexter, the series' subsequent seasons do not follow the novels in the series. Departing from the narrative of Lindsay's second Dexter novel Dearly Devoted Dexter, the show's writer Daniel Cerone said that the writers "didn't see the opportunity in the second book" to adapt it.

The series has received generally favorable reviews from critics, while the second season received universal acclaim. The pilot episode, which aired in the USA on October 1, 2006, attracted more than a million viewers, giving Showtime its highest series ratings in nearly two years. Encouraged by its critical success and high ratings, CBS began broadcasting Dexter for free-to-air on February 17, 2008, thus making Dexter the first program in two decades to air on a national broadcast network after being shown on a premium cable channel. Eight seasons comprising twelve episodes each have been broadcast in the United States and abroad. All eight seasons have been released on DVD and on Blu-ray; box sets containing the first three seasons were released on August 18, 2009, on both DVD and Blu-ray.
