plastic vs metal bottlesYou can't go wrong with promotional drink bottles if you're hoping to attract customers of all stripes. It's that easy and that hard. Why is it hard? Because you're now faced with the dilemma of choosing a drink bottle! There is a dizzying array of selections available for promotional bottles, but the leading contenders are plastic and metal bottles. So, which one? Let us help you through this post.

Pros And Cons: Plastic Bottles

We couldn't tell you which is best for your brand since each bottle has its characteristics and features. So we will tell you the benefits and drawbacks of each to help you weigh your options. Let's start with plastic bottles:


  • Plastic drink bottles aren't just easy on your back when it comes to lifting, but also on your wallet.
  • You can give it any form and colour you desire by moulding and colouring it in different ways.
  • They are a fantastic environmental alternative because many recycled plastic bottles are made of recycled PET (polyethene terephthalate).
  • The vast majority of reusable plastic bottles today do not contain any BPA. Healthline explains that BPA is an estrogen-like substance that may have specific adverse health effects.
  • Disposable PET plastic bottles make ideal giveaways for big-time, one-time events like sporting competitions where a large crowd wants to satisfy their thirst.
  • The Food and Drug Administration (FDA) has determined that plastic bottles produced from PET are safe to drink from.


  • Not all plastic bottles are reusable. As stated in an article published on Envirotech Online, reusable plastic bottles need numbers 2, 4, or 5 written inside the triangle that says "recycling." 
  • Because of the potentially harmful chemicals that can seep from plastic drink bottles, their capacity to be reused is limited after only a few uses. This is especially true when the bottles are subjected to hot drinks.
  • Despite the efforts of "cleaning" plastic bottles rep, plastic, in general, is still the primary cause of pollution in water and air. Moreover, since we first started using it, we still need to fully recover from its damaging effects on us.
  • It is possible to reuse it, but there is a possibility that it will get deformed or leak, mainly if it is used daily for activities such as going to school, working, or exercising.

Pros and Cons: Metal Bottles

Now let's tackle the advantages and disadvantages of drink bottles made from metal like aluminium and stainless steel.


  • Use promotional metal drink bottles to keep beverages at ideal temperatures for longer. Insulation is one of the unique selling points of metal bottles compared to their plastic counterparts.
  • Stainless steel bottles are made from "culinary-grade" materials. This means no recognised health risks are linked with stainless steel bottles.
  • Customisable stainless steel drink bottles are non-reactive, so leaching is not possible.
  • Metal bottles have a higher perceived value than plastic bottles. Therefore, give away branded metal drink bottles to make a positive impression on your recipients.
  • Metal bottles provide outstanding durability and a longer storage life. They are ideal for people who lead active lives or frequently use water bottles.
  • Stainless steel bottles are 100% recyclable. Ensure that the promotional metal you purchase is food grade 18/8 or #304.
  • Both plastic and metal bottles are recyclable, but the latter's manufacturing and recycling processes are more eco-friendly. In addition, metal bottles will not leach even after years of sitting in a landfill. However, this is not the case with plastic bottles.
  • Stainless steel bottles are corrosion- and rust-resistant.


  • Stainless steel bottles may leave some metallic taste in water because of their content, like copper and zinc.
  • Metal bottles are vulnerable to dents and scratches.
  • The bottle may become hot to the touch when filled with hot liquid. So, handle it with care.
  • Because aluminium beverage bottles become reactive when exposed to acidic liquids, they must be lined with epoxy resin. However, the epoxy resin may contain BPA, according to Consumer Reports.
  • Even though aluminium is a metal, bottles made of aluminium have poor insulating qualities.
