Question 1

What plastic materials are Propacks bottles made from?

Accepted Answer

Propacks bottles are available in PET, PETG, and HDPE. PET is lightweight, clear, and the most widely recycled plastic, suited for personal care, household cleaning, and wellness products. PETG offers greater clarity and impact resistance than standard PET, used for prestige cosmetics and fragrance. HDPE is opaque, rigid, and chemically resistant, the standard for shampoo, body wash, household cleaners, and essential oil formulas. All materials are available in PCR formulations to support SB 54 compliance. Propacks caps are also available in PP, which handles a wider range of chemical exposure and is used across personal care and cleaning closures.

Question 2

How do I choose the right bottle volume?

Accepted Answer

Start with your product's fill volume and leave headspace for the closure and any expansion. Propacks bottles range from 1 oz for serums and samples to 32 oz for professional and bulk formats. Consider shelf placement and whether the bottle needs to fit a standard pump or trigger sprayer. Order samples in two or three candidate sizes to confirm fit before committing to a production run.

Question 3

How do I choose the right bottle color?

Accepted Answer

Clear bottles showcase the formula inside and work for toners, serums, and clean-label personal care. Amber blocks UV light and protects light-sensitive formulas like essential oils, tinctures, and vitamins. White opaque gives a clean, clinical look common in skincare and personal care. Natural translucent HDPE suits minimal and refillable product lines. Colored bottles in black, blue, and green are available for brand differentiation and line segmentation. At high PCR percentages, bright white may shift toward off-white and vivid colors may show batch variation. Amber and dark colors are the most consistent at elevated recycled content levels.

Question 4

How do I choose the right bottle shape?

Accepted Answer

Propacks carries cylinder round, Boston round, Bostall, bullet, cosmo, foam, and modern round bottles. Cylinder rounds have straight vertical sides that work with most filling equipment and give maximum label area. Boston rounds are the standard for essential oils, tinctures, and concentrated liquids. Boston tall scales the same profile to shampoo and body wash volumes. Bullet bottles have a tapered shoulder for shelf differentiation. Cosmo bottles are slim and elongated for prestige serums and facial oils. Foam bottles are purpose-built for foaming pump closures. Modern rounds offer a contemporary update on the classic round shape for clean beauty and wellness brands.

Question 5

What is a bottle neck finish?

Accepted Answer

A neck finish is the threaded opening at the top of a bottle that determines which cap or closure fits. It is described by two numbers: the first is the diameter in millimeters, the second is the thread style. A 28-410 finish has a 28mm opening with a 410-style thread. Common neck finishes at Propacks include 20-410, 24-410, 28-400, and 38-400. The wrong neck finish means the cap will not seal correctly. Match both numbers before ordering.

Question 6

What is PCR packaging?

Accepted Answer

PCR packaging is made from post-consumer recycled plastic: material collected from households and businesses after use, processed back into resin, and formed into new bottles and closures. It uses significantly less energy to produce than virgin plastic and reduces the volume of plastic sent to landfill. Propacks bottles and closures are available in rPET and rHDPE to support California SB 54 compliance and your brand sustainability commitments.

Question 7

How do I recycle plastic bottles in California?

Accepted Answer

Plastic bottles marked with resin codes 1 (PET) and 2 (HDPE) are accepted at curbside recycling programs in most California cities. Bottles with a CRV label can be returned to any certified buyback center for a cash refund. Drop-off centers operated by CalRecycle accept a broader range of plastics. Rinse containers before recycling and leave caps on PET bottles. PCR bottles are recycled the same way as virgin plastic bottles.
