The following will elaborate in detail from the core characteristics of disinfectant liquid bottles, production key requirements, as well as the targeted advantages and production precautions of Wanplas extrusion machines.
1. Core Characteristics and Production Key Requirements of Disinfectant Bottle
Disinfectant is a chemical medium, often having corrosiveness and volatility. Some products also need to be stored for a long time, which determines that the disinfectant bottle must possess unique physical and chemical properties, and the requirements for the refinement of the production process are extremely high. The core characteristics and corresponding production requirements mainly manifest in the following aspects:
1.1 Excellent Chemical Stability and Corrosion Resistance
The main components of the disinfectant include sodium hypochlorite, hydrogen peroxide, alcohol, etc., all of which have certain corrosiveness. This requires that the disinfectant bottle be able to resist the erosion of the contents, without swelling, deformation, cracking, or component migration, to avoid contaminating the disinfectant or affecting the product performance. Corresponding production requirements: The bottle material should be selected from food-grade HDPE (high-density polyethylene), PET, etc., which are resistant to chemical corrosion. During the molding process, the material distribution should be uniform, without bubbles, pinholes, etc., to ensure the sealing performance and anti-corrosion ability of the bottle.
1.2 Reliable Sealing Performance and Leak Prevention Capability
Disinfectants are mostly in liquid form and some are volatile. If the packaging bottle has poor sealing performance, leakage and volatilization problems are likely to occur, which not only leads to product loss but also may cause safety hazards due to the contact of the disinfectant with the skin or clothing. Corresponding production requirements: The size of the bottle mouth should be highly precise and have strong compatibility with the bottle cap; the wall thickness of the bottle body should be uniform, especially in the stress concentration areas such as the bottle mouth and bottle shoulder, to avoid sealing failure caused by uneven wall thickness.
1.3 Excellent Mechanical Strength and Drop Resistance
During the production, transportation, storage, and sales processes of the disinfectant bottle, it is inevitable to encounter processes such as handling, stacking, and collision. This requires the bottle body to have sufficient pressure resistance and impact resistance to ensure that it does not break under normal circulation conditions. Corresponding production requirements: After the bottle body is formed, its structure is stable, the wall thickness distribution is reasonable, and there are no weak parts; the bottom design needs to meet the requirements of load-bearing and anti-drop, avoiding product leakage due to deformation or damage at the bottom.
1.4 Compliant with Food Contact Safety Standards
Although disinfectant is not edible, in some scenarios it may come into contact with the skin and mucous membranes. Moreover, the packaging bottles must meet the safety requirements for plastic packaging used for food contact, without any odor or the release of harmful substances. The corresponding production requirements are as follows: The production equipment must have good cleanliness to avoid introducing impurities during the production process; The raw materials should comply with the national standards GB 4806 series, and the molding process parameters should be stable, without generating toxic or harmful substances.
1.5 Adapt to the requirements of large-scale production
The demand for disinfectant products is stable and large in volume. The production of packaging bottles is required to have the characteristics of high efficiency and continuity to meet the delivery needs of customers’ large-scale orders. Corresponding production requirements: The production equipment should have the characteristics of high production capacity and low failure rate, and be able to quickly switch between different bottle sizes to adapt to the production of various types of disinfectants (such as spray type, pour type, large-capacity barrel type, etc.).
