Frequently Asked Questions
Q1: Are these preforms suitable for oral liquid bottle production?
Yes, these 40g PET preforms are designed for blow molding pharmaceutical containers, including oral liquid bottles. PET is a commonly used material for pharmaceutical packaging due to its clarity, shatter resistance, and low interaction with many formulations.
Q2: Can you customize the neck finish or thread size?
Yes, we can customize neck finishes according to your specific closure system. Please provide drawings or standard neck dimensions, and our engineers will adjust the mold accordingly.
Q3: What is the minimum order quantity (MOQ)?
Our MOQ varies depending on the preform design and custom requirements. For standard 40g preforms, the MOQ is typically one 20-foot container. For custom colors or neck finishes, a separate mold investment may be required.
Q4: How do you ensure cleanroom quality during production?
We maintain controlled production areas with regular monitoring of particulate levels. Preforms are handled with minimal contact and packed in sealed bags with desiccants to avoid moisture adsorption and contamination.
Q5: Do you provide samples for testing before bulk order?
Yes, we offer samples. You can request samples to run blow molding trials on your equipment. Please contact our sales team for sample availability and shipping costs.
Q6: What colors are available for the preforms?
Standard color is natural transparent. We also offer amber, blue, or custom colors upon request, subject to order quantity and material availability.
Q7: Is the PET resin food-grade?
Yes, we use PET resin that is suitable for food and pharmaceutical contact. If you have specific regulatory requirements, please inform us so we can verify resin compliance accordingly.
Q8: How long is the production lead time?
For standard preforms, production usually takes 2–3 weeks after order confirmation. Custom neck or color designs may require additional time for mold development.
