Question

Application of silicone on the glass bottle surface during their manufacturing helps in
(A). Maintaining glossy appearance
(B). Prevents breakage
(C). Decreases the noise on contact
(D). Prevents spoilage
Choose the most appropriate answer from the options given below:

• A. (A), (B) and (D) only.
• B. (A), (B) and (C) only.
• C. (A), (B), (C) and (D).
• D. (B), (C) and (D) only.

Hint:

The primary function of a silicone coating on glass is to make it slippery. This slipperiness prevents scratches (which maintains gloss and strength) and reduces noise on the production line. It's a physical protection, not a chemical or microbial one.

Answer 1

The Correct Option is B

Step 1: Concept Overview:
In glass bottle production, surface treatments are applied post-annealing to safeguard the glass and ease handling on filling lines. A common cold-end coating is silicone-based.
Step 3: Detailed Explanation:
The silicone coating lubricates the bottle surface, offering key benefits:
- (A) Gloss Retention: The coating shields the glass from abrasion during contact with machinery and other bottles, preventing dulling scratches and preserving its glossy finish.
- (B) Breakage Prevention: Surface scratches create stress points that weaken the bottle, increasing breakage risk under pressure. The coating minimizes scratches, thus aiding in breakage prevention.
- (C) Noise Reduction: The coating's lubricity enables bottles to slide smoothly on conveyors, reducing friction and noise.
- (D) Spoilage Prevention: The coating lacks antimicrobial or barrier properties. Spoilage prevention relies on food preservation methods (e.g., pasteurization) and bottle seal integrity. This statement is incorrect.
Step 4: Conclusion:
Silicone application helps maintain gloss, prevent breakage, and reduce noise. Therefore, option (B), encompassing (A), (B), and (C), is the correct choice.
