The corrugated box industry is staggering due to tremendous pressure and rise in input costs and the industry’s failure due to raise in prices. Manufacturers of paper mills had raised the prices of Kraft paper, the main raw material for the industry by Rs 1,999-3,999 per tonne. But the final consumers are refusing to pay higher prices. According to Business Standard, the packaging industry margin has reduced to nil due to the rise in the price of raw materials especially Kraft paper that accounts to 70—75% of the total input cost.
Factors that affect the box compression strength are:
- Whether products support the package or not
- The structural design of the carton that includes size and dimensions, supporting elements in the carton design, loading direction and flap design
- Types of secondary packaging
- Storage, transport and conditions such as climatic condition, stacking etc.
- Material properties like compression strength and stiffness
Box compression testing is designed to evaluate the stacking and top load strength of cartons. The machine is available in two models one is digital and the other is computerised. It measures the compression strength in lbf, newtons and kgf. The unit comes with travel protection, TARE and P/H Peak hold facility. The equipment has a strong base made of metal and finished in Autumn Gray and Blue combination and bright chrome and zinc plating to resist corrosion.
