PET Round Shoulder Bottles for Shampoo, Conditioner 50–500ml

50ml–500ml PET Round Shoulder Bottles for Shampoo, Conditioner and Personal Care

Boyu Packaging BY-S3006 is a round PET shoulder bottle series designed for shampoo, conditioner, body wash, emulsion and other personal-care liquids. Available in practical sizes from 50ml to 500ml, the range gives brands one coordinated package for travel, retail and family-size products. Clear or colored PET provides a glass-like appearance with lower transport weight, while custom printing and matched dispensing closures support private-label projects.

Buyers can compare related shampoo bottles, lotion bottles, spray bottles and plastic cosmetic bottles. For drawings, samples and a project quotation, contact Boyu Packaging.

Core Specifications

Data note: the listed 10 × 10 × 20cm and 0.5kg figures are platform single-package data, not verified empty-bottle dimensions or net bottle weight. Use the final technical drawing and pre-production sample for filling-line, carton and freight calculations.

Capacity and Application Guide

Nominal fill, brimful capacity and recommended headspace are different measurements. Ask for a capacity drawing and run a filling trial before confirming label copy. The 480ml and 500ml versions should not be treated as interchangeable until their molds and measurements are verified.

Why Buyers Choose This Bottle Series

• One visual family covers travel, retail and larger refill-oriented pack sizes.
• PET offers good clarity, low transport weight and stronger impact resistance than glass.
• The round shoulder design is familiar to consumers and works well on retail shelves and bathroom counters.
• Multiple color and decoration options support mass-market, salon, hotel and private-label programs.
• Existing molds can reduce development cost when compared with a completely custom bottle structure.

PET Compared with Other Packaging Materials

PET suitability cannot be decided from the ingredient name alone. Fragrance oils, essential oils, solvents, surfactants and active ingredients may affect the bottle, dip tube, gasket or pump. A filled-product compatibility test under expected storage conditions is required.

Choose the Correct Pump

The source data describes a “spray pump,” while the product title emphasizes shampoo and conditioner. These applications normally need different dispensing systems:

• Fine-mist sprayer: suitable for low-viscosity hair mist, room spray, light fragrance or water-like formulas.
• Lotion pump: the practical choice for shampoo, conditioner, emulsion, liquid soap and body wash.
• Higher-output pump: useful for larger 480ml–500ml family, salon or hotel packs.

Confirm neck finish, closure thread, pump output per stroke, dip-tube length, lock style, gasket material and formula viscosity before ordering. Pure essential oils or high-solvent perfume formulas require specific compatibility testing and should not be assumed suitable for a standard PET bottle or pump.

Leak Prevention and Quality Control

A bottle is only leak resistant when the bottle neck, pump, gasket and filling process work as a complete system. Recommended controls include:

1. Confirm the neck finish and closure dimensions against approved drawings.
2. Cut the dip tube to the correct length and angle for each bottle size.
3. Verify pump torque and use the specified gasket or liner.
4. Run upright, inverted and side-leak tests with the buyer’s actual formula.
5. Check priming, output consistency, spray pattern or dosage, and lock performance.
6. Test filled samples at room temperature and elevated temperature, followed by transport simulation.
7. Inspect appearance, capacity, bottle weight, color, print adhesion and carton protection before shipment.

Over-tightening can deform a closure or gasket, while under-tightening can cause leakage. The correct torque range should be established during line trials.

Color, Logo and Decoration

Black, white, clear, green and blue are available reference colors. Custom masterbatch colors should be approved against a physical color sample because PET thickness, transparency and lighting affect the visual result. Branding options include silk-screen printing, digital printing and pressure-sensitive labels. Final artwork should define the print area, Pantone reference, finish, logo position and tolerance.

Silk-screen printing is economical for bold one- or two-color graphics. Digital printing is useful for detailed or multicolor artwork, but adhesion, abrasion and formula resistance still need testing. A decorated pre-production sample is recommended before mass production.

Manufacturing and OEM Process

1. Requirement review: capacity, annual demand, formula, pump type, color, artwork and target market.
2. Component proposal: select the bottle mold, neck finish, pump output and decoration method.
3. Sample evaluation: inspect appearance and run filling, dispensing and compatibility tests.
4. Quotation and approval: confirm unit price, MOQ, tooling, cartons, payment terms and delivery schedule.
5. Pre-production approval: sign off color, print and functional samples.
6. Mass production: bottle molding, closure assembly, decoration and in-process inspection.
7. Final inspection and shipping: verify quality records, carton marks and transport documents.

For an existing bottle mold, new tooling is generally unnecessary unless the buyer changes the bottle structure, neck or geometry. Custom logos and colors normally require artwork plates, screens or color-matching charges rather than a new bottle mold. Fully proprietary shapes need drawing review, mold quotation and additional development time.

MOQ, Price and Lead Time

The stated MOQ is 10,000 pieces. Unless agreed otherwise, buyers should calculate it per capacity, bottle color and print design. Price depends on bottle weight, size, resin, pump specification, decoration colors, order quantity, testing, packing and Incoterm. A useful quotation request includes the target capacity, annual volume, destination port, artwork, formula viscosity and preferred pump.

As a planning reference, available-component samples may take about 3–7 days, decorated samples about 7–15 days, and mass production about 30–45 days after all approvals and deposit. These are estimates, not guaranteed dates; seasonal capacity, decoration complexity and custom tooling may extend the schedule.

Packaging, Shipping and After-Sales

Bottles and pumps should be packed to reduce scratching, dust and deformation. Export cartons may use inner bags, dividers, trays or palletization according to the surface finish and shipping route. Sea freight is economical for volume orders; air freight or express delivery is better for urgent samples and small replenishments. Final carton size, quantity per carton, gross weight and pallet plan must be confirmed after the exact bottle and pump are selected.

Before shipment, agree on an inspection standard and retain approved samples. If a quality issue occurs, provide the purchase order, batch number, carton labels, quantities affected, photos, videos and test details. A clear evidence trail helps the supplier identify whether the issue came from components, assembly, filling, transport or storage.

Safety, Sustainability and Reuse

PET is lightweight and widely recognized in recycling streams, but recyclability depends on local collection rules, color, labels, inks and the mixed-material pump. A design with a removable pump and easy-release label may improve sorting. Recycled content can be discussed where performance, appearance and local regulations permit.

“Eco-friendly” and “non-toxic” claims should be supported by material declarations and market-specific testing. These bottles may be refillable for controlled programs, but consumer reuse should only be recommended after hygiene, cleaning and formula-compatibility risks have been evaluated. Cosmetic or household packaging is not automatically food-grade or suitable for every chemical.

Buyer Checklist Before Ordering

• Confirm whether the required nominal size is 480ml or 500ml.
• Request capacity-specific height, diameter, neck finish, weight and overflow capacity.
• Send the formula viscosity and ingredient restrictions for compatibility review.
• Choose a fine-mist sprayer for water-like products or a lotion pump for shampoo and conditioner.
• Approve the dispensing output, dip tube, gasket and lock mechanism.
• Clarify whether MOQ applies per SKU, color and artwork.
• Approve a filled compatibility test and a decorated sample.
• Confirm AQL, carton specification, Incoterm, production time and remedy procedure in writing.

Frequently Asked Questions

Can the same sprayer be used for shampoo and perfume?

No. Perfume or hair mist normally uses a fine-mist sprayer, while shampoo and conditioner usually require a lotion or higher-output pump. Select the closure using viscosity and compatibility tests.

Is the MOQ 10,000 pieces for mixed sizes?

The listed MOQ is 10,000 pieces, but mixed capacities, colors or artworks should not be assumed. Ask for an MOQ breakdown for every SKU before placing the order.

Are free samples available?

Existing samples are stated as free, subject to availability. The buyer commonly pays courier charges. Custom color or printed samples may carry setup fees.

Are the bottle dimensions and weight fixed?

No. Height, diameter, wall distribution and empty weight vary by capacity and mold. Request the drawing and physical sample for the selected SKU.

How can leakage be reduced?

Match the neck and closure, use the correct gasket and torque, cut the dip tube properly, avoid overfilling, and test the assembled package with the final formula under storage and transport conditions.

Does a custom logo require a new mold?

Usually not. Standard bottles can be decorated with printing or labels. A new mold is required when the bottle shape, neck or structural design changes.

Can the bottle hold essential oils?

Only after testing. Concentrated essential oils and solvent-rich fragrances may affect PET or pump parts. Evaluate the complete pack with the exact formula before production.
