Typical Aquaculture Applications

Application Field	Specific Use Case	Key Requirements
Fry Hatching	Hatching pond cover film, Nursery bags	Uniform light transmission + Insulation & frost protection
Water Quality Management	Floating cover film, Isolation film	Algae inhibition + Evaporation reduction
Disease Prevention & Control	Temporary isolation film, Transport packaging	Prevents cross-infection + Breathability
Overwintering Protection	Overwintering greenhouse film, Surface floating film	Snow/wind resistance + Light transmission & insulation

Technological Frontiers

1.  Functional Integration

       Light & Temperature Control Type: Incorporates light-converting agents (Blue light conversion rate >30%).

       Disease Prevention Type: Contains slow-release antibacterial masterbatch (Bacterial inhibition rate >90% within effective period).

2.  Process Innovation

       Nano-microporous Breathable Film (Controllable moisture permeability: 500-2000 g/m²·24h).

       Biodegradable Fry Film (Biodegradation rate >60% within 180 days).

Selection Considerations

1.  Environmental Suitability

       Northern Overwintering: Choose thicker frost-resistant film (Recommended: >0.08mm).

       Southern Fry Rearing: Opt for thinner, high-transmittance film (0.04-0.06mm).

2.  Certification Requirements

       Aquaculture-specific: Complies with GB/T 4455-2019 standard for polyethylene blown greenhouse film for agricultural use.

       Environmental: Passes RoHS hazardous substance testing.

3.  Cost Control

       Standard Type: Approx. ¥12-15/kg for 0.04mm film.

       Functional Type: Price increases by 30%-50% for added light-converting/antibacterial functions.

This material is gradually replacing traditional PVC films and standard agricultural films, demonstrating unique value in modern aquaculture and industrialized fry cultivation. Customized selection is recommended based on specific farming models (pond/industrial), seasonal climate, and fry species.

Note: The above data is based on industry standards. For specific selection, please consult professional suppliers considering actual farming conditions.
