Let us create a custom, high-experience packaging solution that elevates your brand!

Every time you pick up a shampoo bottle and press it, do you ever wonder: Does the bottle material affect the product's safety? Why are shampoos often sold in transparent bottles, shower gels in frosted bottles, and hand soaps in thicker bottles? The answer lies in the plastic material—different plastic bottle materials vary significantly in corrosion resistance, safety, and compatibility. Choosing the right material ensures your shampoo and conditioner products are both user-friendly and safe.




First, understand: Two core materials commonly used in household chemical bottles—PE and PET.

PE (polyethylene) and PET (polyethylene terephthalate) are the mainstays in shampoo, shower gel, and hand soap packaging:

PE: Features include non-toxicity, strong toughness, and no odor. It releases no harmful substances at room temperature and is suitable for a wide range of applications.

PET: High transparency, moderate hardness, resistance to most shampoo and conditioner ingredients, and high recyclability make it a popular choice for PET bottle manufacturers and brands.

Daily Chemical Bottles: Select Materials by Category for More Accurate Safety and Application

Although shampoo, shower gel, and hand soap all fall into the daily chemical category, their differing ingredients and usage scenarios necessitate different requirements for plastic bottle materials. Choosing the right material ensures both safety and practicality:

Shampoo: PET bottles offer both aesthetics and safety.

Particularly suitable for transparent shampoo, PET bottles clearly showcase the product's texture. PET bottle suppliers precisely control standard bottle opening sizes, such as 38mm, to accommodate lotion pumps and prevent leaks. For larger volumes, purchase thicker versions from wholesale PET bottles for improved drop resistance.

Shower gel:
Bathrooms are humid and prone to collisions. PE bottles are non-toxic, odorless, and resist cracking even after prolonged use. They retain their shape when pressed and resist breaking when dropped, minimizing safety hazards.


Guangdong Hongyuan's PE bottle and PET plastic bottle offer customizable sizes and are cost-effective when purchased in bulk, making them ideal for brands seeking to control costs.

Identifying the material of shampoo and conditioner bottles is simple: simply look for the markings on the bottom of the bottle. PET bottles are labeled "1," while PE bottles are labeled "2" or "4." Bottles labeled "2" are suitable for durable, frosted shower gel bottles and pump-type hand soap bottles; LDPE (low-density polyethylene) bottles are labeled "4," often used for lightweight, travel-sized shampoo and hand soap bottles.

In the production and use of beauty and daily chemical products such as lotions, serums, and shampoos, the stability of the lotion pump directly determines user experience and product reputation. However, in practice, problems such as no dispensing under empty pressure, leakage, and difficulty in rebound occur frequently, affecting production efficiency and potentially leading to consumer complaints.



This article, based on industry production scenarios, breaks down the causes and solutions for 4 core types of failures. It also helps you understand how lotion dispenser pump manufacturers and lotion pump factories can avoid these problems through process control, giving you more direction when choosing a lotion dispenser pump supplier.



01 High Air Pressure Cycles/No Dispensing, Leaking: Core Sealing and Channel Issues



Problem Symptoms: Multiple air pressure cycles are required to dispense liquid when pressing the pump for lotion, or no liquid is dispensed at all; leakage occurs at the connection between the pump body and bottle, or at the top of the pump head, contaminating the bottle or hands.



Solutions



Channel Optimization: Lotion pump supplier Customize the hose length according to the bottle height; a 1-2mm gap between the bottom of the hose and the bottom of the bottle is recommended. For shallow bottles, use a slanted hose with an anti-clogging notch to reduce inlet blockage.



Sealing Control: Plastic lotion pump manufacturers Use aging-resistant and solvent-resistant silicone materials (such as FDA-certified silicone); after assembly, conduct a negative pressure test to ensure no leakage between the one-way valve and the piston ring. This is a mandatory standard for pumps that come into contact with skincare products, such as hand cream pumps.



After-sales emergency handling: If this problem occurs when a consumer uses the hand lotion pump, instruct them to check if the hose is bent. If the pump head is removable, clean any residual solidified liquid (such as clumps of thick emulsion) from the one-way valve.



02 Leakage between the emulsion pump and the bottle neck: Capping torque and size mismatch issue



Problem symptoms: Liquid leaks from the connection between the pump nozzle and the bottle neck, especially noticeable when the bottle is inverted. This is common after production and filling or during consumer use.



Solution:

Production-side torque calibration: The emulsion pump manufacturer should adjust the torque according to the bottle material. For PET bottles, 1.5-2.0 N·m is recommended; for glass bottles, 2.0-2.5 N·m. Calibrate the equipment with a torque tester before each batch of production to avoid uneven torque caused by manual capping.



Improved Size Tolerance: Plastic lotion pump suppliers can offer "adaptive gasket" designs (such as gaskets with raised lips) to accommodate bottle neck height deviations of ±0.5mm, reducing the risk of leakage due to size mismatch.



03 Difficulty in Pump Rebounding After Pressing: Liquid Viscosity and Spring Matching Issue



Problem Description: After pressing pump for lotion, the pump head cannot rebound quickly, or manual assistance is required for reset; the dispensing volume decreases upon secondary pressing, especially noticeable when using thick liquids.



Solution:

Precise Pump Head Selection: Lotion dispenser pump suppliers should provide a "viscosity-pump type" matching table. It is recommended that the purchaser provide a liquid viscosity test report (values ​​at 25℃) in advance; for liquids with seasonal viscosity variations, "wide viscosity adaptable pumps" (300-3000cP) are preferred.



Spring Quality Control: Lotion pump factory Nickel-plated or stainless steel springs must be used to improve fatigue resistance; a "rebound test" is added to each batch, requiring a rebound time of <0.5 seconds after pressing; unqualified products are directly rejected.



04 Emulsion Pump Sleeve Deformation and Cracking: Torque and Low-Temperature Brittleness Issues



Problem Manifestation: After filling and capping, the PP sleeve of the plastic lotion pump shows dents, twisted threads, or direct cracking (commonly at the connection between the sleeve and the pump head); the incidence of this problem increases significantly during winter production.



Solution:

Precise Torque Control: plastic lotion pump supplier Recommends a PP sleeve torque of 1.8-2.5 N·m, and provides torque operation training for customers, and provides manual torque wrenches for calibration.



Low-Temperature Production Plan: Lotion pump factory Pump bodies can be stored in a temperature-controlled warehouse (≥15℃), and warmed up 2 hours before filling; for customers in low-temperature areas, "low-temperature resistant PP sleeves" (with added anti-embrittlement additives) can be provided.



Summary: Choosing the right lotion pump supplier avoids malfunctions at the source. The essence of all malfunctions lies in the mismatch between the "liquid-pump-bottle" compatibility, material characteristics, and process parameters. For buyers, choosing a professional lotion pump supplier and plastic lotion pump supplier is crucial—Guangdong Hongyuan, as a professional lotion pump manufacturer, has been deeply involved in the production of lotion pumps and lotion dispenser pumps for many years, covering a full range of products including hand cream pumps, hand lotion pumps, and plastic lotion pumps. During the production process, from the selection of seal materials and spring force calibration to the negative pressure test and rebound test of each pump body, strict quality inspection standards are implemented to ensure that every emulsion pump leaving the factory meets industry compliance requirements and can accurately adapt to liquids of different viscosities and bottle types. This helps customers avoid common problems such as leakage, non-dispensing, and cracked nozzles from the source, and helps daily chemical products improve user experience and market reputation.
