Key Performance Advantages

1. 1. Quick Dissolution, Zero Residue: Fully dissolves in soil moisture—even at a low temperature of 10℃—without leaving any toxic leftovers.

2. This lets seeds break free rapidly to germinate, eliminating soil contamination and avoiding obstacles to root development.

3. 
   

2. Sturdy & Secure Sealing: Features exceptional tensile strength and load-bearing capacity, resisting tears from friction during transportation, sowing,

and soil covering. Its tight sealing locks in seeds and accompanying nutrients, preventing seed shifting and nutrient leakage.

3. High Flexibility & Moldability: Boasts remarkable ductility to fit various seed spacing and tape structures—whether single-row, double-row,

or mixed-seed arrangements. It adapts effortlessly to automated production molds, ensuring precise and consistent seed positioning.

4. Eco-Conscious & Biodegradable: Crafted from non-toxic PVA material that decomposes into water and carbon dioxide in soil.

This aligns perfectly with sustainable agriculture goals and keeps farmland free from plastic pollution.

5. Moisture Retention for Higher Survival Rates: PVA’s inherent hydrophilic structure creates a temporary "micro-moisture zone" around seeds after sowing.

The film absorbs and locks in soil moisture, maintaining a stable humidity environment crucial for germination—even in arid or fluctuating moisture conditions.

Technical Specifications

Application Areas

Proudly's PVA water-soluble film is the go-to choice for precision seed tape packaging, suitable for a wide range of seeds:

vegetables (carrot, radish, lettuce), flowers (petunia, pansy), and grains (wheat, millet). It is particularly effective for drought-

prone regions or crops sensitive to moisture fluctuations. Additionally, it supports integrated packaging of seeds

with water-soluble fertilizers, microbial agents, and seed-coating products—making sowing more efficient and labor-saving

for large-scale agricultural operations.

Frequently Asked Questions

1. Which seed types work with your PVA film seed tapes?

Nearly all small to medium-sized seeds are compatible, including round seeds (e.g., cabbage), oblong seeds (e.g., carrot), and fine seeds (e.g., lettuce).

For extra-large seeds, we can adjust film thickness and sealing strength for secure packaging.

2. How does PVA film seed tape outperform traditional sowing?

It eliminates manual seed spacing and thinning, cutting labor time by 60%. Its moisture retention feature maintains optimal germination conditions,

boosting survival rates by 25%-30%. It ensures uniform seed distribution (spacing error ≤ 2mm) and enhances germination rates by 15-20% thanks

to protected storage and nutrient supply. Plus, its biodegradability avoids plastic waste from conventional non-soluble tapes.

3. Does the moisture retention affect the film’s dissolution?

No—while the film locks in moisture for germination, it still dissolves completely within the standard 240-second window once soil moisture reaches sufficient levels.

The moisture retention function fades naturally as the film dissolves, avoiding any impact on root growth.
