Toothpaste Tube
A tube, squeeze tube, or collapsible tube is a collapsible package which can be used for viscous liquids such as toothpaste, artist's paint, adhesive, caulk, & ointments. Basically, a tube is a cylindrical, hollow piece with a round or oval profile, made of plastic, paperboard, aluminum, or other metal. In general, on one end of the tube body there is a round orifice, which can be closed by different caps and closures. The orifice can be shaped in many different ways: plastic nozzles in various styles and lengths are most typical. The other end is sealed either by welding or by folding. Typical tube sizes range from 3ml to 300ml. Most tubes are designed to be dispensed with hand pressure, but some are used with a tube key at the base to help roll them up. History John Goffe Rand, an American portrait painter, invented the squeezable metal tube in 1841 for paint."Collapsible", ''The New Yorker'', August 6, 1960, p. 20 Toothpaste in a tube was introduced by Johnson ...

Packaging
Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and personal use. Package labeling (American English) or labelling (British English) is any written, electronic, or graphic communication on the package or on a separate but associated label. History of packaging Ancient era The first packages used the natural materials available at the time: baskets of reeds, wineskins (bota bags), wooden boxes, pottery vases, ceramic amphorae, wooden barrels, woven bags, etc. Processed materials were used to form packages as they were develope ...

Closure (container)
A closure is a device used to close or seal a container such as a bottle, jug, jar, tube, or can. A closure may be a cap, cover, lid, plug, liner, or the like. The part of the container to which the closure is applied is called the finish. Other types of containers such as boxes and drums may also have closures but are not discussed in this article. Many containers and packages require a means of closing, which can be a separate device or seal or sometimes an integral latch or lock. Purpose of closures The closure is often the most critical part of a package, and must fulfill all of the basic functions of packaging in addition to being easy to open and (if applicable) reclose. Depending on the contents and container, closures have several functions: * Keep the container closed and the contents contained for the specified shelf life until time of opening * Provide a barrier to dirt, oxygen, moisture, etc. Control of permeation is critical to many types of products: foods, ...

Mustard (condiment)
Mustard is a condiment made from the mustard seed, seeds of a mustard plant (white/yellow mustard, ''white mustard, Sinapis alba''; brown mustard, ''Brassica juncea''; or black mustard, ''Brassica nigra''). The whole, ground, cracked, or bruised mustard seeds are mixed with water, vinegar, lemon juice, wine, or other liquids, salt, and often other flavorings and spices, to create a paste or sauce ranging in color from bright yellow to dark brown. The seed itself has a strong, pungent, and somewhat bitter taste. The taste of mustard condiments ranges from sweet to spicy. Mustard is commonly paired with meats, vegetables and cheeses, especially as a condiment for sandwiches, hamburgers, and hot dogs. It is also used as an ingredient in many salad dressing, dressings, Glaze (cooking technique), glazes, sauces, soups, and marinades. As a cream or as individual seeds, mustard is used as a condiment in the cuisine of Indian cuisine, India and Bangladeshi cuisine, Bangladesh, the Medi ...

Tomato Paste
Tomato paste is a thick paste made by cooking tomatoes for several hours to reduce the water content, straining out the seeds and skins, and cooking the liquid again to reduce the base to a thick, rich concentrate. It is used to impart an intense tomato flavour to a variety of dishes, such as pasta, soups and braised meat. It is used heavily in Italian cultured food. By contrast, tomato purée is a liquid with a thinner consistency than tomato paste, while tomato sauce is even thinner in consistency. History and traditions Tomato paste is traditionally made in parts of Sicily, southern Italy and Malta by spreading out a much- reduced tomato sauce on wooden boards that are set outdoors under the hot August sun to dry the paste until it is thick enough, when it is scraped up and held together in a richly colored, dark ball. Today, this artisan product is harder to find than the industrial version (which is much thinner). Commercial production uses tomatoes with thick pericarp wa ...

Anchovy Paste
Anchovy paste is a fish paste food product prepared using anchovies as a primary ingredient. It is used as a condiment and as an ingredient in various dishes, such as Scotch woodcock, and is a mass-produced product. It has been used for centuries to provide flavor to foods and as a source of nutrients, and it is a part of the cuisines of Great Britain, Italy, the Philippines and Vietnam. It is a major export product of Morocco. Overview Anchovy is used as a condiment and as an ingredient in various dishes. Basic ingredients in its preparation includes mashed anchovies, vinegar, spices and water, and some commercial preparations are produced using these ingredients. Butter is also sometimes used as a base ingredient, and the resultant product is sometimes referred to as "anchovy butter", and in French as ''beurre d'anchois''.

Watercolor
Watercolor (American English) or watercolour (British English; see spelling differences), also ''aquarelle'' (; from Italian diminutive of Latin ''aqua'' "water"), is a painting method”Watercolor may be as old as art itself, going back to the Stone Age when early ancestors combined earth and charcoal with water to create the first wet-on-dry picture on a cave wall." London, Vladimir. The Book on Watercolor (p. 19). in which the paints are made of pigments suspended in a water-based solution. ''Watercolor'' refers to both the medium and the resulting artwork. Aquarelles painted with water-soluble colored ink instead of modern water colors are called ''aquarellum atramento'' (Latin for "aquarelle made with ink") by experts. However, this term has now tended to pass out of use. The conventional and most common ''support''—material to which the paint is applied—for watercolor paintings is watercolor paper. Other supports or substrates include stone, ivory, silk, reed, papy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrylic Paint
Acrylic paint is a fast-drying paint made of pigment suspended in acrylic polymer emulsion and plasticizers, silicone oils, defoamers, stabilizers, or metal soaps. Most acrylic paints are water-based, but become water-resistant when dry. Depending on how much the paint is diluted with water, or modified with acrylic gels, mediums, or pastes, the finished acrylic painting can resemble a watercolor, a gouache, or an oil painting, or have its own unique characteristics not attainable with other media. Water-based acrylic paints are used as latex house paints, as latex is the technical term for a suspension of polymer microparticles in water. Interior latex house paints tend to be a combination of binder (sometimes acrylic, vinyl, pva, and others), filler, pigment, and water. Exterior latex house paints may also be a co-polymer blend, but the best exterior water-based paints are 100% acrylic, because of its elasticity and other factors. Vinyl, however, costs half of what 100% a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paint Tube
Oil paint is a type of slow-drying paint that consists of particles of pigment suspended in a drying oil, commonly linseed oil. The viscosity of the paint may be modified by the addition of a solvent such as turpentine or white spirit, and varnish may be added to increase the glossiness of the dried oil paint film. The addition of oil or alkyd medium can also be used to modify the viscosity and drying time of oil paint. Oil paints were first used in Asia as early as the 7th century AD and can be seen in examples of Buddhist paintings in Afghanistan. Oil-based paints made their way to Europe by the 12th century and were used for simple decoration, but oil painting did not begin to be adopted as an artistic medium there until the early 15th century. Common modern applications of oil paint are in finishing and protection of wood in buildings and exposed metal structures such as ships and bridges. Its hard-wearing properties and luminous colors make it desirable for both interio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toothpaste
Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis).American Dental Association Description of Toothpaste Owing to differences in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Large amounts of swallowed toothpaste can be toxic. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue. Usefulness Toothpastes are generally useful to maintain dental health. Toothpastes containing fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silk Screen Printing
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ( bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extrusion
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process. Drawing is a similar process, using the tensile strength of the material to pull it through the die. It limits the amount of change that can be performed in one step, so it is limited to simpler shapes, and multiple stages are usually needed. Drawing is the main way to produce wire. Metal bars and tubes are also often drawn. Extrusion may be continuous (theoretically producing indefinitely long material) or semi-continuous (producing many pieces). It can be done with hot or cold material. Commonly extruded materials ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
