Sunscreen Spray is a newly developed simple sunscreen product. It has the advantages of convenient, non greasy, clean and sanitary compared with traditional sunscreen products. If we want to produce sunscreen spray, what kind of filling machine shall we use? Here is a brief introduction of the production process and sunscreen spray filling machine system.
The Production process of Sunscreen Spray
Sunscreen Spray is an aerosol product. It is a mixture of medicine, emulsion or suspension and suitable propellant. It is sealed in a pressure vessel with special valve system. When used, the content is sprayed out of the fog with the pressure of the propellant, which is used for inhaling or directly spraying into the cavity, mucous membrane, skin and sterilizing space.
At present, there are two kinds of filling methods for sunscreen spray, unitary filling and bag on valve filling. In unitary packaging, agent and propellant gas exist in the aerosol tank without separation, while for bag on valve filling, the agent is packed in the bag and the propellant is completely separated from the tank between the bag and the tank. So the product will be safer and more hygienic. So in the cosmetics aerosol industry, the binerary packaging Sunscreen Spray is more popular with consumers.
BOV filling mode refers to the pressure packaging system in which the propellant and the agent are divided into two independent units in the same packaging container. When propellant is used, the energy (pressure) provided by the propellant can be obtained and released from the package in a predetermined form.
It can be divided into two types: separate packaging and barrier pressure packaging. BOV packaging features a bag in the aerosol can. Liquid substances are packed in bags. The gas is located between the aerosol tank and the air bag, which reduces the complexity of the formula, does not release the injector when using, and reduces the impact on safety and environment. The filling method has the advantages of environmental protection, high health level, solution of raw material tank corrosion, gas-liquid incompatibility and so on.
BOV filling spray production process:
Raw liquid production -> bottle arrangement -> valve placement -> filling and sealing of propellant ->forced filling of raw liquid -> weighing -> water inspection -> nozzle fastening -> big cover ->packing and delivery.
