Restrictions on Glass Airless Bottles?

Glass airless pump bottle for cosmetics is a trends  for packaging products that require protection from exposure to air, light, and contaminants. Due to the sustainability and recyclable characteristics of glass material, it becomes a better choice for outer bottles. Some brand customers will choose glass airless bottles instead of all plastic airless bottles (of course, their inner bottle are all plastic, And usually made of environmental protection material PP).

So far, glass airless bottles have not been popularized in production enterprises, because it has some bottlenecks. Here are the two main probelms:

Production cost: At present, the existing glass bottle styles on the market are still very popular. After years of market competition for conventional molds (shape), the price of the normal glass bottle is already very low. Common glass bottle manufacturers will prepare hundreds of thousands of transparent and amber colored bottles in warehouses to reduce production costs. The transparent bottle can be sprayed into the color that the customer wants at any time, which also shortens the delivery time of the customer. However, the market demand for glass airless bottles is not large. If it is a newly produced mold to meet the needs of existing airless bottles, considering that the manufacturing cost of glass is very high and there are many styles, most factories think that it is not necessary to invest in this direction for development.

Technical difficulty: First of all, glass airless bottles must have a specific thickness to maintain their structural integrity and avoid cracking or breaking under pressure. Achieving this thickness can be challenging and may require the use of specialized equipment and techniques. Second, the pump mechanism in an airless glass bottle requires precise engineering to ensure it operates properly and consistently. At present, the airless pumps on the market can only match plastic bottles, because the production accuracy of plastic bottles is controllable and high. The airless pump core requires high precision, the piston requires a uniform inner wall of the bottle, and the airless requires a vent hole at the bottom of the glass bottle, etc. Therefore, this is a major industrial change, and it cannot be completed by glass manufacturers alone. 

In addition, people think too much is glass airless bottles can be heavier than other types of packaging and it is fragile, which makes the products have certain risks in use and transportation.

Topfeelpack believes that factories that produce glass cosmetic packaging should cooperate with manufacturers that specialize in the production of airless plastic bottles, both of which have their own strengths. The airless pump is still equipped with a high-precision plastic inner bottle, and uses environmentally friendly materials, such as PP, PET or their PCR materials. While the outer bottle made of durable and aesthetically pleasing glass, so as to achieve the purpose of replacing the inner bottle and reusing the outer bottle, then achieve the coexistence of beauty and practicality.

After gaining experience with PA116, Topfeelpack will focus on developing more replaceable glass airless bottles, and looking for more environmentally friendly ways.
