Development of Greaseproof Paper from Banana Pseudostem Fiber for Packaging of Butter

ABSTRACT

A study was undertaken to make greaseproof packaging paper using banana pseudostem fiber. Kraft pulp produced from banana fiber was beaten to the freeness of 60°SR and 70°SR, and handsheets (40 ± 1 g/m²) produced were coated with carboxymethyl cellulose (3% and 5% w/v) and sodium alginate (3% and 5% w/v). Handsheets were compared based on differences in their mechanical (tensile index and bursting strength) and barrier properties (contact angle, grease resistance, and air resistance). Significant differences among the treatment were found for all the responses studied. Results obtained for ‘turpentine oil test’ showed that handsheets made at 70°SR and subsequently coated with 3% and 5% carboxymethyl cellulose had grease resistance properties. It was observed that handsheets (70°SR) coated with 5% carboxymethyl cellulose possess maximum tensile index (65.00 ± 3.46 Nm/g), burst strength (3.76 ± 0.21 kg/cm²), contact angle (41.27 ± 0.45º), and air resistance (29.95 ± 0.38 s/100 ml). However, if the amount of coating absorbed per unit area of the sheet is taken into consideration, handsheets produced with 70ºSR pulp freeness in combination with 3% carboxymethyl cellulose coating seem to be more efficient and can be used for packaging of butter.

摘要

开展了一项研究，利用香蕉伪纤维制成防油脂包装纸. 用香蕉纤维生产的卡夫纸浆被击败了60°SR = 70°SR和手板（40±1g/m2）的毛质涂层（3% + 5% w/v）和藻酸钠（3% ~ 5%w/v）. 根据手板的机械性（拉伸指数 + 爆力）和阻隔性能（接触角、耐油脂性 +空气阻力）的差异，对手板进行比较。发现所有被研究的回答在治疗之间有显著差异. “松节油油试验“的结果表明，在70°SR下制作的、随后涂有3%和5%的羧 甲基纤维素的手工布具有抗油脂特性. 据观察，涂有5%卡比甲基纤维素的手板（70°SR）具有最大拉伸指数（65.00±3.46 Nm/g）、爆裂强度（3.76±0.21Kg/cm2）、接触角（41.27±0.45°）和空气阻力（29.95±0.38s/100ml）. 但是，如果将纸张的单位面积吸收的涂层量考虑在内，使用 70° SR 纸浆自由度与 3% 羧 甲基纤维素涂层共同生产的手板似乎更有效，可用于黄油包装.
