Aerosol packaging typically includes tinplate cans and aluminum cans, which are the most common materials used for aerosol containers. However, PE plastic bottles are also increasingly being used in specific applications, especially in certain industries like cosmetics, pharmaceuticals, and personal care. Each type of aerosol packaging has its unique properties and advantages, depending on the product requirements.

For products like pepper spray and other self-defense aerosols, PE plastic bottles offer safety, durability, and convenience. These bottles are lightweight and easy to carry, ensuring that users can quickly access and deploy the spray when needed.PE bottles are used to contain and dispense pepper spray, offering a reliable and effective delivery method for personal defense. The BOV system ensures no leakage or accidental discharge.

PE plastic bottles, especially when combined with Bag-on-Valve (BOV) technology, offer distinct advantages in product safety, environmental sustainability, and user convenience. They are suitable for products that do not require high internal pressure and are designed for easy and controlled dispensing. BOV systems inside PE bottles also ensure minimal product waste, making them ideal for high-value contents like pharmaceuticals, cosmetics, and self-defense sprays.

1.Separation of Product and Propellant:

The BOV system ensures that the pepper spray solution does not come into contact with the propellant, maintaining its chemical stability and effectiveness.

 

2.Consistent Spray Pattern:

BOV technology enables a fine, even mist, which is crucial for self-defense products like pepper spray to cover the maximum area and incapacitate an attacker effectively.

 

3.Full Dispensing:

Since the product is stored in a collapsible bag, the BOV system allows for 100% product evacuation, meaning every drop of the pepper spray can be used.

 

4.360° Spray Capability:

With BOV technology, the pepper spray can be dispensed at any angle, even upside down, ensuring effective use in any self-defense scenario.

 

5.No Need for Pumping or Priming:

Unlike traditional spray bottles, which often require pumping to build pressure, PE bottles with BOV offer an instant and continuous spray without the need for manual pumping. This ensures ease of use and reliability, particularly in situations where quick action is required (e.g., pepper spray for self-defense).

1.Bottle Positioning: The transparent PE bottles with pre-inserted BOV systems are placed onto the filling machine's conveyor.

 

2.Crimping and propellant injection:The valve is crimped and sealed to the top of the PE bottle to create an airtight seal.Then the propellant is injected through the valve stem using a specialized filling head. The propellant fills the space between the bag and the inner wall of the PE bottle, providing the pressure needed to dispense the liquid.

 

3.Liquid injection: The machine equipped with 2 liquid filling heads,then inject the pepper spray solution directly into the bag through the valve stem. This is done under controlled conditions to ensure the exact amount is filled based on product specifications.During the filling process, it's essential to prevent any liquid from entering the area outside the bag (where the propellant will go), as this could affect the spray performance and safety.
