Many brand customers may not realize that the mirror-like glass surface actually hides the challenge of ink adhesion.To solve the above problems and ensure that the brand logo and exquisite patterns can be presented on the skin care glass bottles in a durable and vivid manner, we must pre-treat the glass surface. The following are several methods commonly used in the industry: 1.Why is it difficult for ink to adhere to glass bottles of skin care products? Glass is primarily composed of silicon dioxide (SiO₂), which has a unique structure: silicon atoms (Si) are primarily located within the glass, while oxygen atoms (O) are more exposed on the surface. This structure results in an extremely high surface energy, making the glass highly reactive and easily interacting with surrounding materials. This structure has a high surface energy and is easily interacted with other substances. For example, when exposed to air, it combines with hydrogen in the air to form hydrophilic groups. These hy...

  In the high-end skincare industry, airless pump bottles are no longer an unfamiliar concept. With their superior antioxidant protection capabilities, they have become an indispensable guardian of precious formulas. By isolating the skin from air, airless bottles ensure that every drop of ingredient reaches the skin in its purest and most effective state, preventing oxidation, deterioration, and contamination at the source. This is a key reason why they have become a core choice for high-end skincare packaging.   However, there is a common misconception about airless bottles: the public assumes that the "air-push preservation principle" of airless bottles relies on a movable structure at the bottom, limiting the material to plastic, as glass cannot achieve a airless effect. In fact, double-walled glass airless bottles have long since broken this limitation, achieving a perfect fusion of luxurious feel and vacuum preservation through a sophisticated "bottle within a bottle" d...
