|The difference from the bleached paper
Compared with bleached paper, kraft paper has many unique advantages. For the packaging of home food, such as barbecue or household food, the natural brown of the kraft paper makes the package look warm and nostalgic. The wooden decorating is the main body and the steak restaurant with the flavor of the country. The kraft paper is used to take out the food packaging. Even if it is not in the dining room, it can feel the style of the restaurant. The unique appearance of the kraft paper is also more prominent than the whole white packaging.
|Kraft bubble mailers
Kraft bubble mailers or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process.
Sack Kraft bubble mailers, or just sack paper, is a porous Kraft bubble mailers with high elasticity and high tear resistance, designed for packaging products with high demands for strength and durability.
Pulp produced by the kraft process is stronger than that made by other pulping processes; acidic sulfite processes degrade cellulose more, leading to weaker fibers, and mechanical pulping processes leave most of the lignin with the fibers, whereas kraft pulping removes most of the lignin present originally in the wood. 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.
Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high quality paper where strength, whiteness and resistance to yellowing are important.

|Aluminum is a silvery white light metal. Ductility. The products are usually columnar, rod, flake, foil, powder, ribbon and filiform. A layer of oxide film to prevent metal corrosion can be formed in humid air. The acid treated aluminum powder heated in the air can burn violently and emit a dazzling white flame. Soluble in dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water, but can react with hot water slowly to produce aluminum hydroxide, the relative density of 2.70, elastic modulus 70Gpa, Poisson's ratio 0.33. Melting point 660. Boiling point 2327. It is widely used for its light, good conductivity and thermal conductivity, high reflectivity and oxidation resistance. Do the daily dish aluminum is usually called "steel" or "steel". The thermal expansion coefficient of Al at (25) Shi Wen is 0.0000236mm/ C or 23.6ppm*k-1.|
