How to Identify Safe Plastics for Pets

 In Uncategorized

What is plastic injection

Plastic items are done through a process called injection moulding.  this is a process where plastic melted and injected in a cavity.  When the cavity is filled, the mould is then opened to release the product which is ejected from the cavity.

Depending on the plastic used, the temperature for moulding will be different.  If the melting temperature is too high, some manufactures will add other materials such as BPA and BHT which have a lower melting point.  This is why it’s dangerous when heated or throned in the dishwasher.  The increased temperature will release the contaminants which melts at a lower temperature.

which plastics do we use

We always use number 5 or polypropylene for 2 specific reasons.  While it does not contain BPA nor BHT, it has some other option really interesting to us where this plastic does not break and create sharp edges.  If a dog bites it, it will be perforated but will not break.

We understand that this affects our manufacturing cost but being a family company, we believe that people are willing to pay more for a quality product when it comes to their pets health.

Polypropylene and Aïkiou

We’ve been working with that material for a decade and find that it is by far the safest material on the market presently for feeding your pet.  We feel reassured that we can supply the best quality to customers and their pets.  Polypropylene is not only safer but it’s also less at risk of containing other contaminants which can be harmful to dogs and cats.

Where most of our competitors use a number 7 plastic, we feel that the quality of our pet products sets us apart and to be honest, this lets us sleep better at night knowing that our customers pets are safe and will stay healthy.

1-Polyethylene Terephthalate (bad)
Polyethylene Terephthalate

Polyethylene Terephthalate

Plastic #1 – PET or PETE stands for polyethylene terephthalate, a plastic resin and a form of polyester.

Health Concerns
Studies have found levels of antimony (a toxic chemical) leaching from water bottles that have been placed in heat for prolonged times. Although PETE does not contain BPA or Phthalates, it’s always best to make sure that your water bottles are not temperature abused. PETE plastic should not be reused because cleaning detergents and high temperatures can cause chemicals to leach out of the plastic. Plastic #1 is only intended for one time use.

2-High-density Polyethylene (Good)
High-Density Polyethylene

High-Density Polyethylene

Plastic #2 – High-density polyethylene (HDPE) is a polyethylene thermoplastic made from petroleum. HDPE is hard, opaque and can withstand somewhat high temperatures.

Health Concerns
No known health concerns.

3-Polyvinyl Chloride (bad)
Polyvinyl Chloride

Polyvinyl Chloride

Plastic #3 – Polyvinyl chloride (PVC) is a thermoplastic polymer. Through the use of phthalates, a plasticizer, it can be made softer and more flexible. Read about the harm of phthalates here.PVC can also be found in car interiors and vinyl flooring, resulting in the release of toxic chemicals into the air.

Health Concerns
PVC is one of the toxic plastics that should be avoided.

4-Low-Density Polyethylene (good)
Low-density polyethylene

Low-density polyethylene

Plastic #4 – Low-density polyethylene (LDPE) is a thermoplastic made from petroleum. It can be found translucent or opaque. It is flexible and tough but breakable.

Health Concerns
No known health concerns.

5-Polypropylene (good)
Polypropylene

Polypropylene

Plastic #5 – Polypropylene (PP) is a thermoplastic polymer. It is strong, tough, has a high resistance to heat and acts as a barrier to moisture.

Health Concerns
Most PP are microwavable safe and dishwasher safe. NOTE: microwavable/dishwasher safe only means that the plastic will not warp when heated. It does not imply that it is a healthy practice.

6-Polystyrene (bad)
Polystyrene

Polystyrene

Plastic #6 – Polystyrene (PS) is a petroleum-based plastic. It can either be hard or used in the form of styrofoam.

Where is Polystyrene found?
Polystyrene is widely used in packaging materials and insulation.

Health Concerns
According to the Foundation for Achievements in Science and Education fact sheet, long term exposure to small quantities of styrene can cause neurotoxic (fatigue, nervousness, difficulty sleeping), hematological (low platelet and hemoglobin values), cytogenetic (chromosomal and lymphatic abnormalities), and carcinogenic effects. Styrene is classified as a possible human carcinogen by the EPA and by the International Agency for Research on Cancer (IARC).

7-ABS and others (bad)
ABS and Others

ABS and Others

Plastic #7 can be a little tricky as it stands for “Other” which may or may not contain BPA. It is commonly used to label Polycarbonate (PC). The letters PC may be present with the recycling symbol, which would indicate that the product is made with polycarbonate.

Polycarbonate is derived from BPA. Read more about the harm of BPA here.

Health Concerns
BPA has been found to be an endocrine disruptor. Choose products made with the #1, #2, #4, or #5 recycling codes.
