State Light Industry Bureau puts forward a new variety urgently needed by the paper industry

Product name Main technical characteristics Market demand (1) Low quantitative news paper quantitative 45g/m2, smoothness ≥ 40s, two-sided difference ≤ 15%, whiteness ≥ 56%, crack length ≥ 3400m, opacity ≥ 88%. Can replace imported paper, and is expected to export to the Southeast Asian market. (2) Whiteness of micro-coated printing paper is ≥87%, smoothness is ≥40s, two-sided difference is ≤20%, double-side coating amount is 3～5g/m2, printing surface strength is ≥3m/s. It can be used as an upgrade product for double-sided offset printing papers, with a large market demand. (3) Matte coated paper paper surface gloss <20%, printing gloss> 70%, smoothness> 200s, printing surface roughness ≤ 2.5μm, paper surface gloss is low, printing gloss is high, the screen is clear and eye-catching. The annual demand is about 120,000 tons. (4) High-strength and low-quantity boxboard quantitative 115 ~ 200g/m2, burst index> 3.0 kPa · m2 / g, lateral pressure index 9.2N · m / g, breaking degree> 80 times. The market demand is large and urgently needed to be developed. (5) Low-quantity coated paper quantification 55-56g/m2, smoothness> 150s, whiteness> 76%, printing surface strength> 1.3m/s, opacity> 88%, double-side coating amount 15 to 20g/ M2, ink absorption 15% to 28%. The market demand is large and urgently needed to be developed. (6) High-strength corrugated base paper quantitative 115 ~ 150g/m2, tensile strength ≥ 5kN/m, lateral pressure index 10 ~ 13N · m / g. There is a large market demand and urgent development is needed.

(7) High-grade coated kraft cardboard and coated kraft paper

Cardboard quantitative 180g/m2, coated kraft paper quantitative 100 ~ 120g/m2; smoothness> 100s, tightness ≥ 0.7g/cm3, surface brightness 80%, transverse tensile strength ≥ 4kN/m, printing surface strength ≥ 3m/s, ink absorption 22%~23%, transverse folding ≥ 50 times. Urgent need for development to replace imported products. (8) White kraft paper with a basis weight of 70-90g/m2, transverse tensile strength of ≥3.2kN/m, tensile energy absorption: longitudinal ≥86J/m2, transverse direction ≥100J/m2, 2000 demand of about 60,000-80,000 tons, The future development potential is greater. (9) Grade A cigarette paper

A1 paper: quantitative 27g/m2, longitudinal tensile strength ≥ 0.9kN/m, air permeability ≥ 60Corest, ash ≥ 17.5%.

A2 paper: quantitative 27g/m2, longitudinal tensile strength ≥ 0.9kN/m, air permeability ≥ 70Corest, ash ≥ 17.5%.

About 30,000 tons of high-grade cigarette paper need to be imported each year, which can produce top-notch and strive for export. (10) Car air filter paper quantification 145g/m2, thickness 0.7mm, burst resistance ≥220kPa, air permeability ≥800L/m2·s. High technical requirements, production difficulties, many varieties, small quantities.
