Top 5 High-Efficiency Solution to Enhance Cosmetics Sealing & Product Freshness
Share

In today’s rapidly evolving beauty and skincare market, product safety, freshness, and ingredient stability have become essential brand differentiators. High-performance creams, active formulas, and antioxidant-rich skincare rely heavily on airtight packaging to preserve efficacy. Even minimal air exposure can accelerate oxidation, degrade active ingredients, and compromise product quality.
To address the limitations of manual liner insertion—such as inconsistent sealing, low efficiency, and high labor cost—ZONESUN introduces the ZS-WIM04 Inner Liner Inserting Machine, a high-precision automated solution designed specifically for the cosmetics industry. This machine ensures superior sealing performance, reduces oxidation, and enhances product shelf life.
1. Why Sealing Matters More Than Ever in Cosmetics
Modern skincare formulations contain advanced active ingredients like peptides, retinol, ceramides, and antioxidant complexes. These ingredients are highly sensitive to air exposure.
Poor sealing can lead to:
- Oxidation and color changes
- Texture degradation or separation
- Reduced product efficacy
- Shortened shelf life
- Poor consumer experience
Inner liners provide a protective barrier between the formula and external air. As brands shift toward long-lasting, preservative-friendly skincare, a precise and reliable liner application process becomes crucial.
2. What Is the ZS-WIM04 Inner Liner Inserting Machine?
The ZONESUN ZS-WIM04 is an automated liner inserting system engineered for cream jars, cosmetic containers, and skincare packaging. It automatically picks liners, aligns them with high accuracy, and inserts them into bottle mouths—ensuring consistent sealing quality for every product.
Key functions include:
- Automatic liner picking
- Accurate alignment
- Precision placement
- Integration with full cosmetic filling & packaging lines
It is compatible with plastic, acrylic, PET, and glass cream jars of various sizes.

3. How Automation Improves Product Sealing & Stability
1) Airtight Protection to Reduce Oxidation
The inner liner creates a secondary sealing barrier, protecting sensitive ingredients from oxygen exposure—preserving potency and freshness.
2) Uniform and Consistent Liner Placement
Automated insertion ensures every jar meets quality standards, eliminating human error or liner misalignment.
3) Enhanced Brand Perception
Perfectly sealed products reflect professional craftsmanship and elevate the premium feel of skincare products.
4) Better Consumer Experience
Proper sealing prevents leakage, contamination, and premature drying of creams.
