Creating a that offers exceptional return on investment. strong seal in the film is the first step. To achieve this, a hot knife or hot wire is pressed against the film to weld the seal together. The seal process has three variables: time, temperature, and pressure. Each may be adjusted to suit different film types. Once sealed in a film envelope, the package is passed through a heated shrink tunnel. When heated, the film softens and expands, and as the film cools it shrinks tight. The package exits the tunnel wrapped in a taught, secure, attractive film. There are several films from which you may Clamco 6700GLX Automatic L-Bar Sealer choose.

Considerations for Plastic Food Packaging
PET Packaging Materials Polyethylene terephthalate (PET) is a commonly used plastic in the packaging industry. Common PET products include: • Take-out containers • Baked goods containers • Bottled water • Ketchup • Jars (peanut butter and mayonnaise) • Juices and carbonated drinks • Frozen foods • Cosmetics • Household products Composition of PET Plastic PET is a thermoplastic polymer resin from the polyester family. It is a polymer that is formed by combining modified ethylene glycol and purified terephthalic acid or dimethyl terephthalate. Although its name contains polyethylene, PET does not contain polyethylene. PET Plastic Characteristics • High clarity • Good chemical resistance • Good gas and moisture barrier • High impact resistance • Medium rigidity (semi-rigid to rigid) • Medium scratch resistance • Food contact safety • Temperature tolerance of -50 degrees F to 110 degrees F Origins of PET Plastic Although PET plastic was patented in 1941, the first PET bottle was not produced until 1973. How are PET plastics made? There are two primary processes for producing a PET package. • Thermoforming – a process by which a sheet of PET plastic is heated and shaped using a mold into the desired shape. • Blow Molding – typically used to make containers with narrow mouths Thermoforming vs. Blow Molding PET Plastics Thermoforming allows for custom shaping of PET plastic into any desired shape. PET plastic is often used to produce clamshells, bakery containers or take-out containers. Blow molding is primarily used to create bottles. Why PET -

Cosmetic Packaging to Save the Environment: Future Perspectives
cosmetics Review Cosmetic Packaging to Save the Environment: Future Perspectives Patrizia Cinelli 1,*, Maria Beatrice Coltelli 1,* , Francesca Signori 1, Pierfrancesco Morganti 2 and Andrea Lazzeri 1 1 Department of Civil and Industrial Engineering, University of Pisa, Largo Lucio Lazzarino 2, 56126 Pisa, Italy; [email protected] (F.S.); [email protected] (A.L.) 2 Dermatol Unit, Campania University L.Vanvitelli, Via Pansini 5, 80131 Naples, Italy; [email protected] * Correspondence: [email protected] (P.C.); [email protected] (M.B.C.); Tel.: +39-050-221-7869 (P.C.) Received: 18 March 2019; Accepted: 11 April 2019; Published: 15 April 2019 Abstract: Consumer awareness about the damages that plastic packaging waste cause to the environment, coupled with bio-economy and circular economy policies, are pushing plastic packaging versus the use of bio-based and biodegradable materials. In this contest, even cosmetic packaging is looking for sustainable solutions, and research is focusing on modifying bio-based and biodegradable polymers to meet the challenging requirements for cosmetic preservation, while maintaining sustainability and biodegradability. Several bio-based and biodegradable polymers such as poly(lactic acid), polyhydroxyalkanoates, polysaccharides, etc., are available, and some first solutions for both rigid and flexible packaging are already present on the market, while many others are under study and optimization. A fruitful cooperation among researchers and industries will
