While spray bottles existed long before the middle of the 20th century, they used a rubber bulb which was squeezed to produce the spray; the quickly-moving air siphoned fluid from the bottle. The rapid improvement in plastics after World War II increased the range of fluids that could be dispensed, and reduced the cost of the sprayers because ...
Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. It comprises a can or bottle that contains a payload, and a propellant under pressure. When the container's valve is opened, the payload is forced out of a small opening and emerges as an aerosol or mist. Aerosol spray can
Barbecue sauce in a squeeze bottle. A squeeze bottle is a type of container such as a plastic bottle for dispensing a fluid, that is powered by squeezing the container by exerting pressure with the user's hand.
Filament tape or strapping tape is a pressure-sensitive tape consisting of a pressure-sensitive adhesive coated onto a backing material which is usually a polypropylene or polyester film and fiberglass filaments embedded to add high tensile strength.
Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...
5 Layer co-extrusion of cosmetic "squeeze" tube Typical liquid packaging board. Multi-layered packaging are multilayer or composite materials using innovative technologies aimed to give barrier properties, strength and storage stability to food items, new materials as well as hazardous materials.
Nylon 6 or polycaprolactam is a polymer, in particular semicrystalline polyamide. Unlike most other nylons , nylon 6 is not a condensation polymer , but instead is formed by ring-opening polymerization ; this makes it a special case in the comparison between condensation and addition polymers .
As seen in the table below, Nylon 11 has lower values of density, flexural and Young's modulus, water absorption, as well as melting and glass transition temperatures. Nylon 11 is seen to have increased dimensional stability in the presence of moisture due to its low concentration of amides. Nylon 11 experiences 0.2-0.5% length variation and 1. ...
