Rotogravure is a type of intaglio printing process; that is done by the rotation of the engraved cylinders. Gravure is an industrial printing process capable of consistent high quality printing. Since the Gravure printing process requires the creation of one cylinder for each colour of the final image, it is very expensive and best suited for high volume printing.
Lamination is the technique of manufacturing a material in multiple layers, so that the composite material achieves improved strength, stability, appearance or other properties from the use of differing materials. A laminate is usually permanently assembled by adhesives.
Pouch Making machine is used to convert the Plastic Film in to Bags or Pouches. Plastic bags are used for containing and transporting goods such as foods, produce, powders, ice, magazines, comic books, chemicals and waste. Most plastic bags are heat sealed together.
Slitting is a process in which a coil of material is cut down into a number of smaller coils of narrower measure. Slitting is considered a practical alternative to other methods due to its high productivity and the versatility of materials it can manage. Roll slitting, also known as log slitting or rewind slitting, is a shearing operation that cuts a large roll of material into narrower rolls.
Puncture Strength denotes the relative ability of a material to inhibit the progression of a tear once it has been pierced by a cut or a nick. Tests devised to measure Puncture Strength are generally application-specific. The Puncture Strength will depend on the nature of puncture attempt, with the two most important features being point sharpness and force.
Tear Strength is a measure of how well a material can withstand the effects of tearing. More pecifically however it is how well a material resists the growth of any cuts when under tension, it is usually measured in kN/m.
Seal Strength testing, also known as Peel Testing, measures the strength of seals within flexible barrier materials. This measurement can then be used to determine consistency within the seal, as well as evaluation ofthe opening force ofthe package system. Seal strength is a quantitative measure for use in process validation, process control and capability. Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes’ ability to produce consistent seals.
Industrial Ovens are heated chambers used for a variety of industrial applications of testing, including Testing of Solid Content of Adhesives & Inks, Curing of Laminated Films. Industrial ovens can be used for large or small volume applications, in batches or continuously and a variety of temperature ranges, sizes and configurations.
6 Vacuum Packing is one type of Modified Atmospheric Packaging System. In Vacuum oven one can test the sustainability of pouch under precise vacuum condition with and without temperature. Such type of test gives assurance ofthe performance ofthe pouch after packing material in advance.
Bond strength is one of the main properties of a laminate structure. When the bond strength is measured right after the substrates are brought together, it is referred to as the off- machine bond strength, green strength or green tack. Bond strength after curing the adhesive completely is called cured strength. Bond strength is measured on a Universal Testing Machine. the ratio of the force of friction between two bodies and the force pressing them together.
Tensile Strength is the maximum stress that a material can with stand while being stretched or pulled before necking, which is when the specimen's cross-section starts to significantly stretch. Tensile strength is defined as a stress, which is measured as force per unit area.
