• Quality inspection methods and project
  Accordance with the "new Chang Plastic Co., Ltd. silicone rubber packing tube test", "Name a unified table," "major projects the product regulated series of the standard range table" and "Accessories (cover) series of specifications that the standard range of major projects table ", respectively, of the packaging tube, the end plug, nozzle tip, print inspection.
  
  Test items and requirements
  1, visual
  Observe the appearance of the product, hit the bottle if there dissatisfaction crooked Tsui, high shoulders, wearing Tsui, fracturing, water stains, both inside and outside corrugated, flat nozzle, see the light, cellular and other defects, to plug if the rupture, perforation, playing dissatisfaction, external scratches, dislocation, external water stains and other defects, are regarded as defective. Printed visual inspection, including surface quality, color, panel, pattern definition, chromatic counterpoint and other testing requirements of the dust, the number of black spots in the five below. Pattern of surface dust and black spots less than 1mm, the text face of dust spots is less than 2mm; finished with the same sample of the color contrast; pattern was flipped in the font concavity, no dislocation.
  
  2, light perspective
  Would bottles, bottom plug, the sample on the tip Tsui emergency lights, the light to observe the surface quality, color uniformity, and asked to defect, packaging, white porcelain tube, the end of the threaded plug and nozzle tip without strain.
  
  3, test weight
  Balance scale with the weight of the product tray.
  
  4, the external size detection
  Bottles with a vernier caliper to measure the height, vertical, diameter, interior strength, wall thickness, tube nozzle diameter, nozzle tip diameter, Nei Jing, female, height.
  
  5, A bottle sealing performance test
  Tensile testing machine with computer testing packaging bottle with the bottom plug of the sliding friction.
  6, pressure testing
  Hydraulic pressure testing machine will be transferred 6kg/cm2, put pressure on the bottle 20s, Attorney bottle is broken.
  
  7, high temperature testing
  The oven temperature to 50oC, the product into the 10 hours after the prosecutor whether the product is soft, deformation.
  
  8, low temperature testing
  The freezer temperature to minus 15oC, the product into the 10 hours after the prosecutor whether the product is broken.
  
  9, the sealing performance test B
  Packing the right amount of water bottle fitted with a glue gun to the back cover onto the bottle sealed end 10-30mm, capping the bottle do not generate air pressure, the erection of 48 hours, to observe whether leakage.
  
  10, the Ministry of toughness testing thread Tsui
  The built-in water bottles were dropped from 1.5m and 2m higher than the level of vertical drop, the Ministry of Attorney threaded nozzle is broken.
  
  11, the material composite toughness testing
  (This rule only for 60g standard bottles) will be frozen bottles placed under the rolling tire, the prosecution is broken.
  
  12, print quality test pattern layout
  The printed pattern observed with a magnifying glass and font, no flash, saw teeth.
  
  13, printed ink adhesion test
  Balanced against the friction of the two products 20 times, the ink does not fall off.
  
  
  Soft Lab
  The company has advanced detection equipment quality flexible packaging, raw materials and products can be a variety of physical and chemical properties of the test, so that effective monitoring of quality flexible packaging products. Are the main test items include: yield strength, the effective tensile strength, tensile strength, elastic modulus, peel strength, heat seal strength, friction coefficient, aging and pressure properties.
  
  Mainly with testing instruments are: film thickness, the electronic testing machine, friction tester, heat seal tester, constant humidity box, freezer, oven, etc., and punch card machines with aluminum, the aluminum-on performance test .
