At Unique Packaging we take quality testing & assurance on high priority. We conduct multiple tests to ensure that packaging is qualitative & sustainable.
As per the report by Research Markets, Indian Corrugated Box Industry grew up to a CAGR of 23.3% in terms of revenue till 2018 with 18000 organized and unorganized players in operations. Also, since it is a low capital intensive business there many new players entering in this market making your job difficult to decide which company to choose for packaging your product/s.
Here are some of the qualifying tests that we conduct at Unique Packaging to ensure that boxes can endure pilferage, weights and/or any other contingency situation.
1. Burst Test
Bursting or Mullen test is conducted to check the strength of the walls of corrugated box whether it can bear the pressure. We use rubber diaphragm to apply pressure on the walls until it bursts. We expand the diaphragm using hydraulics and as the diaphragm expands, the corrugated board bursts under pressure.
2. Edge Crush Test
Each side of the corrugated box is made up of grooves and ridges covered between thin sheets so that the boxes can bear pressure from one direction. Edge Crush Test helps us ascertain the same.
3. Paper Grammage and Thickness
Grammage and thickness are the two most fundamental properties of the corrugated fiberboards that determine the quality of the box. There is no “best” grammage or thickness mentioned in corrugated boxes specifications and it is completely based on your requirements.
When more padding is required, a box with a higher thickness is used. The flutes of the corrugated board are larger and pack more air in them. Thin boards with dense flutes have a high grammage. Such boxes are needed when the packaging should be more compact and rigid.
4. Puncture Resistance Test
5. Box Compression Test
Box compression test, helps ascertain how much load the box can take from the top which gives us a good idea in terms of how many boxes can be placed on top when stacking them for transportation without damaging the box at the bottom.
6. Moisture Test
This test is required to ensure standard moisture in corrugated boxes which is done with the help of Moisture tester machine. Standard moisture should be between 6-8% and for every 1% increase in this moisture %, the compression strength of the cartons will fall by 6.5%.
