PET Boston Round Bottles with Silver Caps

PET Boston Round Bottles With Silver Caps combine a stable Boston round shape with lightweight PET construction, offering good impact resistance and clear product visibility for liquid packaging. Compared with glass containers, PET helps reduce package weight and the risk of breakage during handling and transportation. The threaded neck is matched with the corresponding silver screw cap for reliable closure and convenient filling.

HYT Packaging provides standard and customized options for different packaging projects. Bottle capacity, color, neck finish, cap specifications, and surface decoration can be adjusted according to the product and filling requirements. Labeling, silk-screen printing, and other finishing options are also available for bulk orders.

What Buyers Check Before Ordering

Neck Finish and Cap Fit

The neck finish must match the selected screw cap for proper thread engagement and sealing. Common options include 28-400 and other neck specifications according to the bottle design. For customized projects, bottle-neck drawings or physical samples can be provided for fitting verification.

Clear or Amber PET

Clear PET provides product visibility and is suitable for general applications. Amber PET offers additional protection from light and can be considered for light-sensitive formulas. The appropriate color should be selected according to the product's storage and light-resistance requirements.

Bottle and Closure Performance

Bottle dimensions, neck finish, cap fit, and liner position all affect the final packaging performance. For bulk orders, assembled samples can be checked before production to confirm the bottle-cap combination.

Damages caused by improper transportation, wrong filling operation or end-user misuse are excluded from return scope. Please inspect goods within 15 working days after cargo arrival.

Packaging & Storage

PET bottles should be stored in a clean, dry, and ventilated environment. Keep them away from direct sunlight, excessive heat, and chemical contamination.

During transportation and warehouse handling:

· Keep cartons dry and away from ground moisture.

· Avoid excessive stacking pressure.

· Protect bottles from deformation and impact.

· Keep products in their original packaging before use.

· Check cartons and bottle condition before filling.

For automated filling, the filling temperature and product compatibility should be confirmed before production.

After-Sales & Usage Guidance

Customers should inspect the quantity, bottle appearance, dimensions, and cap condition after receiving the goods. For manufacturing-related issues, provide photos, videos, affected quantities, and batch information for evaluation.

Damage caused by improper storage, transportation, filling operation, or use with incompatible closures is normally evaluated separately from manufacturing defects.

FAQ

Q: What sizes of PET Boston round bottles with silver caps are available?

A: 15, 30, 50, 100, 250, and 500ml, in clear or amber PET, all on the standard 28-400 neck. Custom sizes are available on request.

Q: Why choose amber PET?

A: Amber PET blocks UV in the 290–450nm range, protecting light-sensitive contents like essential oils and nicotine liquids. It is a shelf-life decision, not just a color preference.

Q: Do the silver caps seal PET Boston round bottles well?

A: Yes - the silver PP cap carries a liner, and assembled bottles are leak-tested (filled, inverted, pressurized) before packing. Cap torque is batch-tested at 15–25 in-lbs.

Q: Can I get dropper caps instead of screw caps?

A: Yes - dropper and disc-top caps fit the same 28-400 neck, so one bottle can serve multiple formats. We supply bottle and cap as a matched system.

Q: What is the MOQ?

A: 10,000 pieces standard, lower on stock sizes. Request a quotation with your volume, color, and cap type for firm pricing.
