Flat Square PETG Lotion and Shampoo Bottles with Pump 200–500ml

200ml–500ml Flat Square PETG Lotion and Shampoo Bottles with Pump

Boyu Packaging’s flat square PETG bottle combines a slim rectangular footprint, angled edges and a matched lotion pump for modern haircare, skincare and personal-care packaging. Available in 200ml, 300ml, 400ml and 500ml sizes, it gives brands a coordinated format for shampoo, conditioner, body lotion, shower gel and compatible liquid formulas. The broad front panel provides useful space for branding, while PETG delivers a clear, substantial appearance without the transport weight or breakage risk of glass.

Core Specifications

Important data note: the supplied “16 × 16 × 146cm” single-package size is inconsistent with a 200–500ml bottle and is likely a listing error. The stated 0.12kg may also refer to a packed sample rather than the empty bottle. Do not use either figure for filling-line or freight calculations until Boyu provides the capacity-specific drawing, empty weight and carton list.

Capacity Selection

Nominal volume, brimful capacity and recommended filling volume are not the same. Allow suitable headspace and complete a filling trial before approving the label claim.

Key Features and Buyer Benefits

• Premium clarity: PETG offers a clean, glass-like presentation for visible formulas and colored products.
• Space-efficient profile: the flat rectangular body can fit more efficiently in cartons and on shelves than a wide round bottle.
• Brand-friendly panels: broad front and back faces provide practical areas for screen printing or labels.
• Distinctive angled edges: the geometric outline creates a more architectural, premium appearance.
• Coordinated sizes: four capacities help brands build one visual family across several product categories.
• One-hand dispensing: a lotion pump improves dosage control and convenience in bathrooms, salons and hotels.

PETG Compared with PET, HDPE and Glass

PETG is not automatically compatible with every cosmetic formula. Fragrance, essential oils, alcohol, surfactants and active ingredients can affect the bottle, dip tube, gasket or pump. Test the complete package with the actual formula under expected storage conditions.

Pump Performance, Sealing and Convenience

The standard lotion pump is intended for products such as shampoo, conditioner, liquid soap and lotion. Buyers should confirm pump output per stroke, neck finish, gasket material, dip-tube length, lock style and viscosity range. A fine-mist spray pump is only appropriate for water-like formulas and should not be specified for conventional shampoo or thick conditioner.

For travel or e-commerce, choose a secure lock or clip and test the unlocked and locked pump in the final carton. A flat bottle also requires stability testing because the narrow side profile and a tall pump can affect tipping behavior.

How to Reduce Leakage

1. Match the bottle neck finish, pump thread and gasket to the approved specification.
2. Set a controlled capping torque; both under-tightening and over-tightening can cause failures.
3. Cut the dip tube to the correct length and angle for every capacity.
4. Leave suitable headspace and avoid filling product into the sealing area.
5. Run upright, side and inverted leak tests using the actual formula.
6. Complete heat, cold, vibration and transport simulation before mass shipment.
7. Recheck pump priming, output consistency and leakage after storage testing.

Color and Logo Customization

The bottle can be supplied clear or in a customized color. Transparent tints allow the product to remain visible, while opaque or darker colors can create stronger shelf differentiation. A physical color standard is recommended because resin thickness, transparency and lighting change the visual result.

Silk-screen printing is suitable for clean logos and limited-color artwork. Labels may be more practical for detailed regulatory text, short multilingual runs or variable SKUs. Buyers should approve the print area, Pantone references, logo position, registration tolerance, adhesion and rub resistance on a decorated sample.

Manufacturing and Quality Inspection

PETG bottles are normally produced by molding a preform and forming the final bottle in a controlled mold. The pump is assembled separately from PP and internal components. Decoration and final assembly follow after dimensional and appearance checks.

Recommended inspection points include resin and color verification, bottle weight, capacity, height, base size, neck dimensions, wall distribution, flat-panel distortion, scratches, contamination, print adhesion, pump output, torque, leakage and carton protection. Retain an approved limit sample so that acceptable appearance and color are clear to both buyer and supplier.

Target Markets and Use Scenarios

This series is suitable for skincare and haircare brands, contract fillers, private-label companies, salons, spas, hotels, distributors and importers. Typical uses include retail shampoo and conditioner sets, coordinated bathroom amenities, salon back-bar products, body lotion, shower gel and hand wash. Highly concentrated oils, aggressive solvents or unusually thick products require separate material and pump evaluation.

MOQ, Pricing and Tooling

The standard MOQ is 10,000 pieces, normally calculated per capacity, bottle color and artwork. Unit price depends on capacity, bottle weight, PETG grade, pump construction, color, printing, packing quantity and Incoterm. Send the formula viscosity, expected annual volume, destination port and artwork when requesting a quotation.

If an existing mold and neck finish meet the project, a new bottle mold is usually unnecessary. Custom colors and printing may require color-matching, screen or plate charges. A proprietary shape, altered shoulder or different neck requires engineering review, new tooling and a longer development schedule.

OEM Development Process

1. Brief: confirm capacity, formula, pump type, color, decoration, quantity and target market.
2. Selection: match an existing bottle mold, neck finish and pump.
3. Sampling: review appearance, dimensions, filling and dispensing performance.
4. Compatibility testing: test the actual formula in the assembled package.
5. Pre-production approval: sign off color, print and functional samples.
6. Production and QC: mold, decorate, assemble and inspect the order.
7. Shipment: approve packing, carton marks, documents and shipping method.

Existing samples generally require about 3–5 days when components are available. Custom samples usually take about 7–15 days. Mass production is normally planned for approximately 30–45 days after sample approval and deposit, but the confirmed schedule depends on decoration, component availability and order season.

Packing, Shipping and After-Sales

Cartons, inner bags, dividers, trays or pallets can be selected according to the bottle finish and transport route. Sea freight is normally preferred for volume orders; air freight or express delivery is practical for samples and urgent replenishment. Final carton dimensions, gross weight and loading quantity should be based on the approved bottle and pump—not the unverified platform listing.

Before shipment, agree on the inspection standard and keep approved samples. For an after-sales claim, provide the purchase order, batch number, carton label, affected quantity, photos, videos and test conditions. This allows Boyu Packaging to distinguish between component, filling, transport and storage issues. Learn more about Boyu Packaging.

Safety, Sustainability and Reuse

PETG is lightweight and break resistant, which can reduce transport damage compared with glass. However, local recycling acceptance varies, and the assembled package contains several materials. A removable PP pump and easy-release label can make separation easier. Any BPA-free, recycled-content, food-contact or environmental claim should be supported by the relevant material declaration or test report for the final specification and destination market.

The bottle can be refilled in a controlled program, but reuse is not automatically suitable for every cosmetic product. Cleaning, microbial control, pump wear and formula compatibility must be considered before promoting repeated consumer reuse.

Buyer Checklist

• Request the drawing, empty weight and overflow capacity for the selected size.
• Confirm the 200ml base measurement and all dimensions of the larger sizes.
• Provide formula viscosity and ingredients that may affect plastics or elastomers.
• Approve pump output, lock type, dip tube, neck finish and gasket.
• Clarify whether MOQ applies to each capacity, color and print design.
• Test filled, decorated samples before mass production.
• Confirm AQL, print tolerance, carton specification, Incoterm and delivery date in writing.

Frequently Asked Questions

What capacities are available?

The series is offered in 200ml, 300ml, 400ml and 500ml. Confirm nominal and overflow capacity on the approved drawing.

Is PETG better than PET for shampoo bottles?

PETG normally offers a more substantial, glass-like appearance, while PET is usually lighter and more economical. The best choice depends on brand positioning, budget, formula compatibility and recycling requirements.

Can a spray pump be used instead of a lotion pump?

Yes, but only for compatible low-viscosity products. Shampoo, conditioner and body lotion normally require a lotion pump with suitable output.

Can different capacities be mixed to reach 10,000 pieces?

Do not assume mixed sizes are accepted. MOQ is normally applied per capacity, color and artwork; request an SKU-by-SKU confirmation.

Does logo printing require a new mold?

No. A standard bottle can usually be screen printed or labeled. New tooling is required only when the bottle structure, shape or neck is changed.

How is leakage controlled?

Boyu matches the neck, pump and gasket, controls capping torque and dip-tube length, and performs functional checks. The buyer should also complete filled-product storage and transport testing.

What information is needed for an accurate quotation?

Provide capacity, quantity, formula viscosity, bottle and pump color, artwork, decoration, destination and preferred trade term.
