Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Bruce 2024-12-1 019 Bruce 2024-12-1 09:13
Low lignin is important to the resulting strength of the paper, as the hydrophobic nature of lignin interferes with the formation of the hydrogen bonds between cellulose (and hemicellulose) in the fibers Bruce 2024-12-1 017 Bruce 2024-12-1 09:13
mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood Bruce 2024-12-1 017 Bruce 2024-12-1 09:13
Acidic sulfite processes degrade cellulose more, leading to weaker fibers Bruce 2024-12-1 020 Bruce 2024-12-1 09:13
Pulp produced by the kraft process is stronger than that made by other pulping processes. Bruce 2024-12-1 017 Bruce 2024-12-1 09:13
Sack kraft paper (or just sack paper) is a porous kraft paper with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability. Bruce 2024-12-1 021 Bruce 2024-12-1 09:12
Kraft paper or kraft[1] is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process Bruce 2024-12-1 028 Bruce 2024-12-1 09:12
One-step biaxial orientation eliminates the MDO stretching part and uses a tenter frame with accelerating clips. Bruce 2024-12-1 028 Bruce 2024-12-1 09:12
The system consists of an extruder, MDO equipment (two or more sets of rolls running at different speeds), and a tenter frame for the MDO. Bruce 2024-12-1 027 Bruce 2024-12-1 09:12
The widely used two-step biaxial orientation process is the combination of the MDO and TDO as mentioned in Section 4.12.1.1 Bruce 2024-12-1 027 Bruce 2024-12-1 09:12
Biaxially oriented films exhibit exceptional clarity, very high tensile properties, improved flexibility and toughness, improved barrier properties, and can be relatively easily made shrinkable. Bruce 2024-12-1 030 Bruce 2024-12-1 09:12
Moreover, our dedication to innovation in packaging aims at reducing our environmental impact and promoting the use of state-of-the-art materials. Bruce 2024-12-1 020 Bruce 2024-12-1 09:11
Cellulose for industrial use is mainly obtained from wood pulp and cotton. Bruce 2024-12-1 025 Bruce 2024-12-1 09:11
Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Bruce 2024-12-1 027 Bruce 2024-12-1 09:11
Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Bruce 2024-12-1 036 Bruce 2024-12-1 09:11
Cellulose is mainly used to produce paperboard and paper. Bruce 2024-12-1 028 Bruce 2024-12-1 09:10
Cellophane is 100% biodegradable and made from a renewable source. Bruce 2024-12-1 029 Bruce 2024-12-1 09:10
With good clarity, mechanical property, and human food safety, this film material is widely applied in food packaging, cigarette packages, and decoration purposes. Bruce 2024-12-1 031 Bruce 2024-12-1 09:10
Because of its regular linear structure and array of hydroxyl groups, cellulose-based films tend to be tough and flexible and resistant to fat and oil. Bruce 2024-12-1 025 Bruce 2024-12-1 09:10
t is usually made from the fiber plants such as cotton, wood, hemp, etc, which are the same materials for producing paper. Bruce 2024-12-1 023 Bruce 2024-12-1 09:10
