Plastic or glass? How to choose the right container

Glass offers a total barrier and a perception of higher value; plastic packaging weighs about ten times less, does not break in transit, meaningfully lowers freight cost and loss, and in Mexico is recycled intensively. The right choice depends on your product, your sales channel and your logistics.

Plastic containers in PET, HDPE and PP from our catalogue

We distribute plastic packaging — PET, HDPE, PP and laminate — and we do not sell glass. That is exactly why this page states plainly where glass is the better answer: if your product needs glass, switching would cost you more than it saves.

Where glass wins

  • Absolute barrier. No gas transfer and no migration into the product. It is the standard for spirits, wine and long-life preserves.
  • Very high temperatures. Sterilization and hot filling above the range most plastics tolerate.
  • Perceived value. In premium categories the glass itself carries part of the brand message.
  • Inert and reusable. Many refill cycles without the material degrading.

Where plastic wins

  • Weight. Around one tenth of its glass equivalent, with a direct effect on freight — especially on long lanes or shipments to the United States.
  • Breakage. Practically no loss from impact in transit, warehouse or shelf. Broken glass also means line stops and a workplace safety issue.
  • Cost per unit and per pallet. Usually lower, and more units fit on the same pallet.
  • Safety. Suitable for beaches, pools, gyms, hospitals, schools and events where glass is banned.
  • Design. Shapes glass cannot produce, in clear, amber, white and black.
  • Food grade. FDA 21 CFR documentation available for the model and resin you specify.
  • Temperature. Some products in our catalog do withstand high temperatures — there are containers and closures designed for hot filling — so do not rule plastic out on that basis without asking us. Not every model supports it: we confirm the temperature range of the specific model when we quote.

Material matters as much as the format: PET for clarity and beverages, HDPE for chemicals and detergents, PP for closures, temperature and products that require it, and laminate for flexible packaging. The materials guide compares barrier, chemical resistance and service temperature for each resin.

Sustainability

Recycling glass means melting it at very high temperatures, which consumes far more energy than reprocessing PET, and in Mexico PET has a real collection and recycling chain behind it. We are directly in that business through our sister company P4P (Plastics for People). See the detail on packaging with recycled content and PCR resin.

Side-by-side comparison

Glass versus plastic packaging compared across eight criteria.
CriterionGlassPlastic
WeightHeavy; drives pallet and shipment weight.Roughly one tenth of the glass equivalent.
Breakage riskBreaks on impact in transit, warehouse and shelf; causes line stops and a safety hazard.Virtually no loss from impact; it dents or deforms instead of shattering.
Oxygen and light barrierAbsolute barrier: no gas transfer, no migration. The standard for long shelf life.Good to very good depending on resin and color; metallized laminate comes close to glass.
Fill temperatureHandles sterilization and hot filling above the range of most plastics.Model-dependent: some containers and closures are built for hot fill. We confirm the range when we quote.
Freight costHigh: you pay for weight, especially on long lanes.Low: less weight and more units per pallet.
Cost per unitUsually higher.Usually lower.
Use safetyRestricted at beaches, pools, gyms, hospitals, schools and events.Allowed in all of those settings.
Shelf perceptionReads as higher value; the reference in premium categories.Very good with clear, amber, white or black finishes and shapes glass cannot produce.

When switching from glass to plastic makes sense

  • Sauces and dressings sold through retail or food service.
  • Honey and other viscous products where a squeeze format helps.
  • Creams and cosmetics, where PET reads as clean and premium in clear or amber.
  • Powdered supplements, where a wide jar and case pack economics matter.
  • Cleaning products, a natural fit for HDPE.
  • Beverages, where weight and breakage decide the freight bill.
  • Anything shipped by parcel carrier or crossing into the United States.

When it does not

  • Premium spirits, where glass is part of the product itself.
  • Preserves that go through sterilization above what plastic tolerates.
  • Any category where the customer buys the glass as much as the content — changing it would cost you more than the freight it saves.

If that is your case, stay with glass. We would rather tell you than sell you the wrong container.

Frequent questions

Is plastic packaging food safe?
Yes. Our standard PET, HDPE and PP containers are food grade, and FDA 21 CFR documentation is available on request for the specific model and resin you quote.
How much does a plastic container weigh compared to glass?
As a practical reference, a plastic container weighs roughly one tenth of its glass equivalent. That means less weight per pallet, lower freight cost and easier handling in the warehouse.
Are there plastic containers that withstand hot filling?
Yes. Part of our catalog — containers and closures, mostly PP — is designed for hot fill. Not the whole catalog supports it: we confirm the temperature range of the specific model when we quote, before you commit.
Which is easier to recycle, PET or glass?
Recycling glass requires melting it at very high temperatures, which consumes far more energy than reprocessing PET. In Mexico, PET also has a real, highly active collection and recycling chain, not just the theoretical possibility of being recycled.

Compare with real models

Look at the plastic equivalent of what you use today: 133 bottle models, 44 jar models and the materials guide with barrier, chemical resistance and service temperature per resin. Each product page lists volume in fl oz, neck finish and case pack.

We also provide samples so you can test the change — fill, cap torque, label and shipping — before committing to a production run.
