Plastic Milk Container
Plastic milk containers are plastic containers for storing, shipping and dispensing milk. Plastic bottles, sometimes called jugs, have largely replaced glass bottles for home consumption. Glass milk bottles have traditionally been reusable while light-weight plastic bottles are designed for single trips and plastic recycling. Materials Packaging of milk is regulated by regional authorities. Use of food contact materials is required: potential food contamination is prohibited. Strict standards of cleanliness and processing must be followed. The most common material in milk packaging is high density polyethylene (HDPE), recycling code 2. Low density polyethylene (LDPE) and polyester (PET) are also in use. Polycarbonate had been considered but had concerns about potential contamination with bisphenol A. Container forms Blow molded plastic milk bottles have been in use since the 1960s. HDPE is the primary material, but polyester is also used. A wide variety of milk bottle d ...

Bottle Of Milk
A bottle is a narrow-necked container made of an impermeable material (such as glass, plastic or aluminium) in various shapes and sizes that stores and transports liquids. Its mouth, at the bottling line, can be sealed with an internal stopper, an external bottle cap, a closure, or induction sealing. Etymology First attested in 14th century. From the English word ''bottle'' derives from an Old French word ''boteille'', from vulgar Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... word ''boteille'', from vulgar Latin ''butticula'', from late Latin ''buttis'' ("cask"), a Latinisation (literature), latinisation of the Greek language, Greek βοῦττις (''bouttis'') ("vessel"). Types Glass Wine The glass bottle represented an important development in the history of wine, because, when combined with a high-quality stopper such as a cork, it allowed long-term aging of wine.

Square Milk Jug
The square milk jug is a variant of the one-gallon (3.785 liters) plastic milk container sold in the United States. The design was introduced in the summer of 2008 and is marketed as environmentally friendly because of the shape's advantages for shipping and storage (better cube efficiency). Square milk jugs are stackable and 9% more can be shipped in the same space. They also eliminate the need for milk crates, which are required for traditional bell-shaped jugs. Pouring technique The technique used to pour milk from a square milk jug is different from that of a traditional milk jug. A Sam's Club representative suggests "tilt it slowly and pour slowly" and a dairy owner in Yerington, Nevada, where some square milk jugs are filled, described the pouring technique as "rock-and-pour instead of a lift-and-tip". Design Environmental benefits and cost savings are the primary stated benefits of square milk jugs, although there are noticeable trade-offs. Because more milk fits on each ...

Bagged Milk
A milk bag is a flexible plastic pouch used to package milk and is used in some areas instead of a hardened milk jug. Usually one of the corners is cut off to allow for pouring, and the bag is stored in a pitcher. A typical milk bag contains approximately of milk in South America, Iran, Israel, and continental European countries, while in Canada they contain , and in India, . In the Baltic rim countries and some Eastern European countries, similar bags may also be seen used for packaging yogurt or kefir. Benefits For producers, it is easier to vary portion size when sealing bags than cartons, as well as lowering the cost of packaging. Milk bags also take up less space in the garbage. For consumers, bags typically allow for smaller portion sizes. This theoretically reduces the risk of spoilage, as well as the space and location of storage in the fridge. Recycling While milk bags use less plastic than standard plastic bottles or jugs, empty bags are often not accepted f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quality Management System
A quality management system (QMS) is a collection of business processes focused on consistently meeting customer requirements and enhancing their satisfaction. It is aligned with an organization's purpose and strategic direction ( ISO 9001:2015). It is expressed as the organizational goals and aspirations, policies, processes, documented information, and resources needed to implement and maintain it. Early quality management systems emphasized predictable outcomes of an industrial product production line, using simple statistics and random sampling. By the 20th century, labor inputs were typically the most costly inputs in most industrialized societies, so focus shifted to team cooperation and dynamics, especially the early signaling of problems via a continual improvement cycle. In the 21st century, QMS has tended to converge with sustainability and transparency initiatives, as both investor and customer satisfaction and perceived quality are increasingly tied to these factors. ...

Reverse Logistics
Reverse logistics encompasses all operations related to the upstream movement of products and materials. It is "''the process of moving goods from their typical final destination for the purpose of capturing value, or proper disposal. Remanufacturing and refurbishing activities also may be included in the definition of reverse logistics''". Environmental concerns and the development of green supply chain management practices have increased the relevance of reverse logistics. Academic and professional interest in reverse logistics has grown considerably in recent decades. The first use of the term "reverse logistics" in a publication was by James R. Stock in a white paper titled ''Reverse Logistics'', published by the Council of Logistics Management in 1992. The concept was further refined in subsequent publications by Stock (1998) in another Council of Logistics Management book, titled ''Development and Implementation of Reverse Logistics Programs'', and by Rogers and Tibben-Le ...

Life Cycle Analysis
Life cycle assessment (LCA), also known as life cycle analysis, is a methodology for assessing the impacts associated with all the stages of the life cycle of a commercial product, process, or service. For instance, in the case of a manufactured product, environmental impacts are assessed from raw material extraction and processing (cradle), through the product's manufacture, distribution and use, to the recycling or final disposal of the materials composing it (grave). An LCA study involves a thorough inventory of the energy and materials that are required across the supply chain and value chain of a product, process or service, and calculates the corresponding emissions to the environment. LCA thus assesses cumulative potential environmental impacts. The aim is to document and improve the overall environmental profile of the product by serving as a holistic baseline upon which carbon footprints can be accurately compared. The LCA method is based on ISO 14040 (2006) and I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aseptic Processing
Aseptic processing is a processing technique wherein commercially thermally sterilized liquid products (typically food or pharmaceutical) are packaged into previously sterilized containers under sterile conditions to produce shelf-stable products that do not need refrigeration. Aseptic processing has almost completely replaced in-container sterilization of liquid foods, including milk, fruit juices and concentrates, cream, yogurt, salad dressing, liquid egg, and ice cream mix. There has been an increasing popularity for foods that contain small discrete particles, such as cottage cheese, baby foods, tomato products, fruit and vegetables, soups, and rice desserts. Aseptic processing involves three primary steps: thermal sterilization of the product, sterilization of the packaging material, and conservation of sterility during packaging. To ensure commercial sterility, aseptic processing facilities are required to maintain proper documentation of production operations, showing t ...

Shelf Life
Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. In other words, it might refer to whether a commodity should no longer be on a pantry shelf (unfit for use), or no longer on a supermarket shelf (unfit for sale, but not yet unfit for use). It applies to cosmetics, foods and beverages, medical devices, medicines, explosives, pharmaceutical drugs, chemicals, tyres, batteries, and many other perishable items. In some regions, an advisory ''best before'', mandatory ''use by'' or ''freshness date'' is required on packaged perishable foods. The concept of expiration date is related but legally distinct in some jurisdictions. Background Shelf life is the recommended maximum time for which products or fresh (harvested) produce can be stored, during which the defined quality of a specified proportion of the goods remains acceptable under expected (or specified) conditions of distribution, storage and display.

Thermoforming
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be stretched into or onto a mold and cooled to a finished shape. Its simplified version is vacuum forming. In its simplest form, a small tabletop or lab size machine can be used to heat small cut sections of plastic sheet and stretch it over a mold using vacuum. This method is often used for sample and prototype parts. In complex and high-volume applications, very large production machines are utilized to heat and form the plastic sheet and trim the formed parts from the sheet in a continuous high-speed process and can produce many thousands of finished parts per hour depending on the machine and mold size and the size of the parts being formed.

Pitcher (container)
In American English, a pitcher is a container with a spout used for storing and pouring liquids. In English-speaking countries outside North America, a jug is any container with a handle and a mouth and spout for liquid – American "pitchers" will be called jugs elsewhere. Generally a pitcher also has a handle, which makes pouring easier. Ewer is an older word for a pitcher or jug of any type, though tending to be used for a vase-shaped pitcher, often decorated, with a base and a flaring spout. The word is now unusual in informal English describing ordinary domestic vessels. A notable ewer is the America's Cup, which is awarded to the winning team of the America's Cup sailing regatta match. Etymology The word ''pitcher'' comes from the 13th-century Middle English word ''picher'', which means earthen jug. The word ''picher'' is linked to the Old French word ''pichier'', which is the altered version of the word ''bichier'', meaning drinking cup. The word's origin goes as fa ...
