Polyvinyl chloride bottles

A 0.1% w/v aqueous solution of benzoic acid has been reported to be stable for at least 8 weeks when stored in polyvinyl chloride bottles, at room temperature. 

Which molecular weight resin (as measured by limiting viscosity number) is best suited for the manufacture of polyvinyl chloride bottles, 0.68 or 1.12 ... 

Liquor packaging presents an additional problem in that containers for distilled spirits must be approved by the Bureau of Alcohol, Tobacco, and Firearms (BATF, under the Treasury Department), as well as being provided for in 21CFR. BATF for a long time did not condone the use of rigid polyvinyl chloride bottles for such, because of the vinyl chloride monomer (VCM) situation of over a decade ago. However, polyethylene terephthalate liquor bottles now abound.

Polyvinyl chloride (PVC) is one of the most widely used thermoplastics. It can be extruded into sheets and film and blow molded into bottles. It is used in many common items such as garden hoses, shower curtains, irrigation pipes, and paint formulations. 

Other polymers that we blow mold include polyvinyl chloride and polycarbonate. We use the former to make cooking oil and household cleaning product bottles. The latter is used to make the large water bottles that we see in water coolers. 

Why do polyethylene terephthalate bottle manufacturers not use any polyvinyl chloride for closures or labels on the bottle ... 

Several types of bottles are manufactured from polyvinyl chloride via blow molding. Examples include clear bottles used for cooking oils, cosmetic bottles, and clear spice bottles. 

Leaf and grass bags, upholstery, bottles, drainage pipe, roofing, flooring, coated fabrics, and siding are all made from polyvinyl chloride, PVC is the consumer product plastic. 

Administer bivalirudin via an IV line. Do not mix other medications with bivalirudin before or during administration. No incompatibilities have been observed with glass bottles or polyvinyl chloride bags and administration sets. 

In this section we demonstrate the performance of the proposed model on an industrial-scale case study. Instead of considering the full scale petrochemical network which may have limited application, we consider a special case of the integration problem. Although the proposed formulation covers the full scale refinery network and petrochemical systems, the case study will consider the integration of a petrochemical complex for the production of polyvinyl chloride (PVC) with a multi-refinery network. PVC is one of the major ethylene derivatives that has many important applications and uses, including pipe fittings, automobile bumpers, toys, bottles and many others (Rudd et al., 1981). 

Another important packaging development area is plastic. Various plastics have been and continue to be used high- and low-density polyethylene (HDPE, LDPE), polyvinyl chloride (PVC), polystyrene (PS) and various barrier plastics. These can be formed into bottles of conventional shape or fed into machines producing form-fill-seal packages, typically cups. 

Thermoplastics consist of long chains of molecules, in the case of PE these are unbranched. Many of these chains together form a tangle which is more difficult to unravel the more branched the chains are. The branches are like hooks which cause the molecules to catch. Under the influence of relatively small external forces chains and parts of chains can slide across each other. PE is for instance used to make containers, chemical tubing and blow-moulded bottles. Some other thermoplastics are polypropylene (crates), polyvinyl chloride PVC (pipes) and polystyrene (foam). 

When you must use plastics, choose 2 high-density polyethylene (HDPE), 4 low-density polyethylene (LDPE), and 5 polypropylene (PP). These types of plastics are not known to leach harmful chemicals. Avoid 3 polyvinyl chloride (PVC), 6 polystyrene (PS), and 7 polycarbonate. Plastic bottles made from 1 polyethylene terephthalate (PET or PETE) are for single, not multiple, use. 

PVC (polyvinyl chloride, aka vinyl) Food containers, some plastic or cling wraps, some soft bottles Avoid You know by now how we feel about PVC. Plus some PVC plastics contain softening phthalates (see page 36 for a reminder). If you use plastic wrap, don t let it touch your food. 

Photooxidation Diffusion Chemical changes due to photochemical reactions Introduction of contaminants from man-made materials, such as solvents from polyvinyl chloride (PVC) materials and PVC cement, plasticizers, and phthalates from polyethylene and polypropylene materials Protection from exposure to light, use of amber glass bottles Use of inert materials (PTFE, fiberglass-reinforced epoxy materials) steam-cleaning of groundwater well components prior to installation... 

Awareness of the problem developed in the mid 1970s when it was found that mineral waters sold in polyvinyl chloride (PVC) bottles contained measurable amounts of vinyl chloride monomer. Vinyl chloride is a known carcinogen. The Codex Alimentarius Committee on Food Additives and Contaminants has set a guideline of 1 ppm for vinyl chloride monomer in PVC packaging and 0.01 ppm of the monomer in food (Institute of Food Technologists 1988). Another additive found in some PVC plastics is octyl tin mer-captoacetate or octyl tin maleate. Specific regulations for these chemicals exist in the Canadian Food and Drugs Act. 

Few conclusive studies have identified the source or spread of Brettanomyces within the vineyard except for use of contaminated equipment. Contaminated and improperly sanitized crush equipment, drains, barrels, transfer hoses, valves, pumps, and bottling equipment can all act as sources for further infection (33). Harper (67) found the interior surface of plastic (polyvinyl chloride, polyethene, and plasticised nylon) pipes used commonly in the brewing industry maintained a variety of bacteria and yeast populations, including Brettanomyces. 

All rubbers, glasses, and plastics are polymers. You are probably familiar with natural polymers like cellulose (the building block of plant fibers) and synthetic polymers like polyethylene (plastic milk cartons), polyisoprene (automobile tires), polyethylene terephthalate (soft drink bottles), polymethyl methacrylate (Plexiglas ), polyvinylidene chloride (transparent plastic wrap), polytetrafluoroethylene (Teflon ), and various polyesters (fabrics). Polyvinyl chloride, the polymer shown earlier, is used to make rigid pipes, house siding, and protective coverings for automobile seals and dashboards, among many other applications.
