The zip is bonded to the packaging by a heat activated adhesive that is pre-applied to the backing of the zip. The first resealable packaging with a zipper was licensed in the United States by Minigrip® in 1954. "Ziplock" is now used as a noun or adjective in relation to plastic bags using this type of seal regardless of manufacturer. [2]
BFS-packaged eye drops for single use. Blow-Fill-Seal, also spelled as Blow/Fill/Seal, in this article abbreviated as BFS, is an automated manufacturing process by which plastic containers, such as bottles or ampoules are, in a continuous operation, blow-formed, filled, and sealed.
The typical machine is loaded with a continuous flat roll of plastic film, which has usually had labeling and artwork applied. Plastic is the most commonly used packaging material in the food industry, but the technology can be used to form continuous metallized foil/film, paper, and fabric product containers by changing the edge sealing/seaming methods.
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 engineering, also package engineering, packaging technology and packaging science, is a broad topic ranging from design conceptualization to product placement. All steps along the manufacturing process, and more, must be taken into account in the design of the package for any given product.
Reusable packaging is manufactured of durable materials and is specifically designed for multiple trips and extended life. A reusable package or container is "designed for reuse without impairment of its protective function."
Induction sealing also offers advantages when sealing to glass: Using a conduction sealer to seal a simple foil structure to glass gives no tolerance or compressibility to allow for any irregularity in the glass surface finish. With an induction sealer, the contact face can be of a compressible material, ensuring a perfect bond each time.
Packaging operations can be designed for variable package sizes and forms or for handling only uniform packages, where the machinery or packaging line is adjustable between production runs. Certainly slow manual operations allow workers to be flexible to package variation but also some automated lines can handle significant random variation.
