Material: 100% virgin wood pulp treated via a sulfuric acid parchmentization process (vegetable parchment, not animal-derived); a specialized agricultural paper used for fruit bagging, flower protection, and pollination isolation during breeding.
This vegetable parchment paper is designed specifically for agricultural use, featuring water resistance and weather durability. The base paper undergoes a parchmentization process that gelatinizes and densifies the fibers, resulting in a material that is water-resistant, moderately breathable, rain-resistant, and possesses high wet strength. It is available as finished fruit bags or in large master rolls for further processing by customers, serving to protect fruit during the growing season and provide isolation for breeding and pollination.
Key Performance Characteristics
High wet strength; resistant to breaking when wet
Does not disintegrate or fall apart after exposure to rain; withstands long-term outdoor rain exposure and regains strength upon drying; offers a longer service life than standard fruit-bagging paper or tracing paper.
Water and acid-rain resistance
Protects against erosion from rain and acid rain, thereby reducing fruit diseases and spotting.
Semi-translucent with balanced breathability
Allows soft light transmission without creating a stifling, airtight environment; maintains stable internal temperature and humidity to promote fruit coloration and growth; controlled breathability helps reduce mold and rot.
Resistant to sunlight, aging, and folding
Does not easily become brittle or powdery under intense outdoor sun exposure; withstands repeated bending during bagging and sewing processes without cracking.
Neutral paper composition with no harmful leaching
Does not contaminate the fruit skin or leave residues after harvesting; available in low-fluorescence, agricultural-grade formulations.
Suitable for slitting, printing, heat-sealing, and sewing into bags; customizable light transmission, basis weight, and color.
Standard Technical Specifications
• Basis weight: 45–70 gsm (predominantly 50–60 gsm)
• Form: Jumbo rolls, slit small rolls, or flat sheets
• Color: Natural white; light yellow or other pale shades available upon request (agricultural fruit-bagging paper is typically not deeply dyed)
• Light transmission: Semi-transparency levels adjustable based on crop requirements
• Operating environment: Outdoor temperatures of -10°C to 65°C
1. Fruit bagging: Protective bagging for young fruits-such as grapes, pomegranates, kiwifruit, pears, citrus, and mangoes-to prevent pest and bird damage, minimize direct pesticide residue, and improve the smoothness and appearance of the fruit skin.
2. Breeding and pollination isolation bags: Used in hybrid breeding for vegetables, melons, fruits, flowers, corn, and rice to exclude foreign pollen and ensure breeding purity.
3. Protection during flowering, seedling shielding, and isolation packaging for greenhouse fruits and vegetables.
Paper Type Distinctions
1. Agricultural-grade parchment (for fruit/vegetable bagging): Parchmentized, with extremely high wet strength and rain resistance; semi-transparent yet breathable, suitable for long-term outdoor use. Prioritize agricultural-grade paper; do not use food-grade or industrial parchment, as costs and formulations differ.
2. Standard tracing paper (sulfuric acid paper): Merely semi-transparent with poor wet strength; it disintegrates easily in the rain and is unsuitable for long-term outdoor fruit bagging.
3. Standard kraft fruit-bagging paper: Highly light-blocking and opaque with poor breathability; it lacks the semi-transparent, soft-light effect characteristic of parchment paper.
