“…After this shaping, the starch-based glue is usually applied to the wave tops and adherence of the flute to pre-heated liner dities against all kind of damages during storage and transport. Therefore, the maintenance of strength of cardboard during storing, marketing and distribution of horticultural commodities is needed to take into consideration [6]. The weight, type and properties of the outer, inner and intermediate papers forming the corrugated cardboard are of great importance as they are directly related to the box performance.…”

P aper and paperboard sheet materials obtained from an interwoven lattice of cellulose fibers made of cellulosic material like wood, linen or cotton [1]. The most important application of paper and paperboard is in corrugated paperboard packages. A corrugated cardboard consisting of a single corrugated layer sandwiched between two liner layers (Fig. 1). This product consists of a combination of the three layers stronger than each layer is individually owned. In addition to single wall, double wall and triple wall corrugated cardboards are also in current use. Double wall corrugated cardboards consist of gluing five layers of paper; one inner, one outer, one intermediate liner paper and two fluted papers and forming a double wall corrugated cardboard. Corrugated medium part of the cardboard is called as flute (Fig.2). Variations in flute height and number of flutes per unit of length defined as flute type (A, B, C, E)

“…Pathare et al 7 found that compressive strength of packaging decreased by 618 N per each 1% increase in paper moisture content when ventilated packaging was subjected to cold storage (−0.5°C and 90% RH), decreasing box compressive strength by about 50% of the initial value. Hung et al 8 found a higher loss of resistance: box compression resistance was reduced by about 70% after 7 days of storage (6°C, 95% RH). However, to the best of our knowledge, there is little data about the effect of low temperature, high RH and long periods of storage on the resistance of the paper components of corrugated board.…”

The high humidity produced by the ripening of fruit and vegetables during refrigerated storage and transport leads to a noticeable loss of strength of corrugated board packaging. Increasing use of recycled fibres in the manufacture of corrugated board further reduces box compression strength. Adding virgin fibres to the furnish composition of liner paper could solve this problem. Various proportions of unbleached virgin eucalyptus and pine fibres were added to a recycled furnish used to manufacture liner paper for corrugated board. Laboratory sheets of each fibre blend were characterised by tensile, bursting and compressive strength. The change in the strength properties and moisture content of the sheets during refrigerated storage at 6°C and high relative humidity (90% RH) was also studied. The results showed that paper strength improved with the proportion of virgin fibres added. Pine fibres yielded higher increments than eucalyptus fibres in tensile and burst indices, whereas both fibres improved compression strength at a similar rate. After 4 h of exposure at refrigerated storage, the paper strength properties decreased considerably, in particular compression strength, which showed a loss of about 70% compared to the reference value. The percentage of strength lost compared to the value in standard conditions was influenced only by exposure time at low temperature and high RH. However, an increase in the amount of pine fibres added enhanced the remaining tensile and burst indices.

“…Nanomists could bring a number of benefits to the field of postharvest crop storage. Hung et al (2010a) have demonstrated that the strength of corrugated cardboard is well-preserved under a nanomist environment with high relative humidity. The aim of the present paper is to investigate the effect of nano-and ultrasonic mists on the control of weight loss and several postharvest quality attributes of three types of horticultural produce stored under high relative humidity environment.…”
