01 Multilayer Bottle Structures
Choose the layer structure that matches your chemical formulation, target shelf life and local packaging requirements.
Layer 1 — Outer protection
HDPE / PP structural layer with UV stabilizers; provides rigidity and impact strength.
Layer 2 — Adhesive
Bonds the structural layer to the barrier layer and prevents delamination.
Layer 3 — EVOH / PA barrier
Main oxygen / solvent barrier; dramatically slows permeation of aggressive chemicals.
Layer 4 — Adhesive (chemical-resistant grade)
Keeps the inner contact layer bonded even when in contact with solvents or surfactants.
Layer 5 — Inner chemical-contact layer
Specialty PE / PP formulation resistant to the exact agrochemical formulation.
- Outer structural layer
- Middle barrier layer (EVOH or PA)
- Inner contact layer
For moderately aggressive formulations or shorter storage periods.
- Outer structural layer
- One adhesive layer
- Barrier layer
- Inner chemical-resistant layer
Good balance for most liquid insecticides, herbicides and fungicides.
- Outer layer + two adhesive layers
- Strong EVOH/PA barrier
- Premium inner contact layer
Recommended for concentrated pesticides, long shelf life or very aggressive solvents.
02 Agro-Chemical Applications
KSY multilayer machines support the production of containers for a range of crop-protection and plant-care products.
Insecticides & Pesticides
Protect pyrethroids, organophosphates and neonicotinoids from oxygen / moisture attack while keeping aggressive solvents away from the outer package structure.
Herbicides & Weed Control
Resist swelling, stress-cracking and migration often caused by surfactant-heavy glyphosate or 2,4-D type formulations.
Fungicides & Bactericides
Offer a stable inner surface and barrier protection so moisture does not trigger premature activation of sensitive actives.
Liquid Fertilizers & Nutrients
Handle acidic and alkaline formulations by choosing the right inner material and layer stack.
03 Machine Features for Pesticide Lines
Independent Extruder Control
Each layer has an independent extruder, giving precise thickness control and quick material change between runs.
Chemical-Resistant Design
Contact parts, die heads and platens are manufactured with chemical-compatible surfaces to avoid contamination and corrosion in the production area.
Recipe Memory
Store complete barrel-zone temperatures, screw speed and die-gap settings for each bottle and layer combination.
Consistent Wall Thickness
Servo-driven parison programming gives accurate wall distribution, saving material without losing strength.
Easy Material Change
Multi-layer purging routines and grooved feed throats make switching between HDPE, PP, EVOH or PA faster.
Compatible with Downstream QC
Can be integrated with leak testers, vision inspection and weighing systems for high-volume pesticide packaging.
