A paper bag or paper sack is a preformed container made of paper, usually with an opening on one side. It can be one layer of paper or multiple layers of paper and other flexible materials. A bag is used for packaging and/or carrying items. Many shopping bags, paper grocery bags, or other light duty bags have a single layer of paper. A variety of constructions and designs are available.
A plastic bag or pouch is a type of flexible packaging made of thin, flexible, plastics film. Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, chemicals and waste.
Bags are also made with carrying handles, hanging holes, tape attachments, security features, etc. Some bags have provisions for easy opening and re-closing. Some bags are sealed and can only be opened by destroying the packaging, providing some tamper-evident capability. Bags can be made with a variety of plastics films. Polyethylene (LDPE, LLDPE etc) is the most common. Other forms, including laminates and coextrusions can be used when the physical properties are needed.
Adhesive tape can be one of many varieties of backing materials coated with an adhesive. Several types of adhesives can be used: "Pressure sensitive tape", "PSA tape", "Self stick tape", "Sticky tape" consists of a pressure sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil. It is sticky (tacky) without any heat or solvent for activation and adheres with light pressure. These tapes usually require a release agent on their backing or a release liner to cover the adhesive. Sometimes, the term "adhesive tape" is used for these tapes.
Biopolymers are polymers produced by living organisms. Cellulose, starch and chitin, proteins and peptides, and DNA and RNA are all examples of biopolymers, in which the monomeric units, respectively, are sugars, amino acids, and nucleotides.
CMYC – cyan; magenta; yellow; key
Injection Moulding - The process of converting plastic pellets by using heat and pressure to inject the molten material into a water-cooled mould. The equipment can produce a number of products in the one injection.
Flexible Packaging - Covers a wide range of packaging that can be single and multi-layered and is supplied in reels or bags. It can be paper/poly/foil or nylon or a combination of materials which are supplied either plain/printed/coated and/or laminated to provide long shelf life properties. End products packaged include confectionery, snack foods, frozen foods, soups and pharmaceuticals.
Gravure Printing - This printing medium is the transfer of ink from an etched cylinder such as a sunken surface to the substrate, eg. paper/film/foil. The equipment is a multi-station (up to nine) printing machine to print and/or coat up to eight colours on to a fast-moving web of material.
HDPE - High-density polyethylene.
Kraft - This term describes the natural, unbleached corrugated fiberboard used in making cartons. Linerboards - Linerboards form the inner and outer facings of corrugated fibre boxes and are chosen for their structural and/or decorative properties. They can be made from white or brown, kraft or recycled fibres, or a blend of both.
LDPE - Low density polyethylene.
Metallising - Applying, through a vacuum process, a thin aluminium layer onto flexible plastic film substrates used to package a variety of foods.
Offset/Lithographic Printing - This printing medium is the transfer of ink from a sensitised plate, offset to a rubber blanket then transferred to the substrate. The equipment is a multi-station (up to eight) printing machine to print and/or coat up to six colours on to sheets or a fast-moving web.
PET - Polyethylene Terephthalate.
Printing - Most printing of corrugated board is done by the flexographic method, which can be thought of as a sophisticated method of printing with rubber stamps. Flexo printing is used for both pre-print and post-print applications. Most printing on corrugated boxes is done in the conversion process after the corrugated sheet is produced, ie. post-printing. Pre-printing refers to the process of printing a design or pattern onto a roll of paper before it proceeds to the corrugating stage. This process is typically used for high volume jobs where quality printing is required.
PP - Polypropylene.
Plastic dishes - It is produced from polystyrene and other materials. As a rule, it is intended for the disposable use. It is widely used at fast food restaurants (фастфудах) and at the organisation of picnics. Some kinds of plastic are not intended for hot dishes or for alcoholic drinks as at thermal effect or at contact to spirit allocate harmful substances.
Polyvinyl chloride, (IUPAC Poly (chloroethanediyl)) commonly abbreviated PVC, is a thermoplastic polymer. It is a vinyl polymer constructed of repeating vinyl groups (ethenyls) having one of their hydrogens replaced with a chloride group.Polyvinyl chloride is the third most widely produced plastic, after polyethylene and polypropylene.
PVC - Polyvinyl chloride.
Recycling involves processing used materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from land filling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to virgin production.
Security seals are affixed to vehicles, chemical drums, airline duty free trolleys, utility meters and a range of boxes and various other applications, in order to provide tamper evidence and a level of security (level dependent on the seal). This can help to detect theft or contamination - accidental and deliberate. Security seals can be split into two main groups: single use and reusable.
Stretch wrap or stretch film is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound. In contrast, shrink wrap is applied loosely around an item and shrinks tightly with heat. It is frequently used to unitize pallet loads but also may be used for bundling smaller items.
TDPA Additives - when added to PE, PP and PS resins, causes the plastic to degrade at a controlled rate. The degradation is triggered by exposure to ultraviolet light (sunlight), elevated temperatures or mechanical stress. The shelf life and service life of degradable and biodegradable plastic products incorporating TDPA™ can be customized based on customer requirements ranging from a few months to years depending on the type and amount of TDPA™ added to the plastic resin.
Thermoforming - The process of shaping a plastic sheet of styrene or PVC under heat and pressure.
