Glue makes your life and the lives of those around you so much easier. The best thing about it is that you don\u2019t even know it\u2019s there, but it\u2019s always working to\u00a0literally<\/em>\u00a0keep your world together. The circuit board inside your smartphone? Held together with silicone glue. That awesome pair of shoes that you got on sale? They\u2019re held together by glue. Even that juicy steak that makes you mouth water just by looking at it is held together by glue! That\u2019s right, even some of the food that you enjoy is held together by a food-safe adhesive, but this isn\u2019t the only instance in everyday life where adhesives and foodstuff interact with one another. This being said, let’s have a look at what food-safe glue is, how it works, and what some of the best food-safe glue products on the market are.<\/p>\n

 <\/p>\n

What Is the Definition of Food-Safe Glue?<\/h2>\n

It pretty much goes without saying that most of us understand what a food-safe glue is, after all, we wouldn\u2019t want a glue to come in contact with our food or things that come into direct contact with our food and make us sick. This being said, there is a more technically accurate definition of food-safe glue as described by the Food and Drug Administration (FDA). What is this description you ask?<\/p>\n

\"Legal<\/p>\n

Legally, a food-safe glue is described as a food contact substance intended for use as a component of material used in the manufacturing, packing, transporting, or holding of foodstuff, if such use is not intended to have a technical impact on such food. Now, that is a mouthful, and although it might be a bit reductive, this basically means that if a glue affects the food in any way other than intended, it is not considered food safe.<\/strong><\/span><\/p><\/blockquote>\n

\"Industrial<\/p>\n

So, while you\u00a0could<\/em>\u00a0use any adhesive on food, this doesn\u2019t mean that you\u00a0should.\u00a0<\/em>Certain adhesives have the potential to contaminate the food they\u2019re used on, which can lead to rot, poisoning, and generally making the food unfit for human consumption. We say human consumption because we\u2019re usually the ones that eat food that has glue attached to it, but this doesn\u2019t mean you should feed contaminated food to animals either.<\/p>\n

\"Toxic<\/p>\n

This doesn\u2019t just apply to adhesives used in meat processing plants either. Any adhesive that will come into direct contact with food needs to follow the formula set out by the FDA in their regulations of materials act section 175.300. This means that any packaging that uses glue, whether it be an in-store container, refrigeration unit, or temporary storage device, must only use adhesives synthesized using the above-mentioned guidelines or the food contained inside them will legally be considered unsafe for human consumption.<\/p>\n

\"Glued<\/p>\n

That\u2019s a lot to take in, right? Well, it’s even trickier to implement considering that everyone is concerned about their bottom line, which is why most manufacturers and distributors of foodstuff tend to use food-safe containers to transport their products to avoid adhesive contact. This being said there are loads of food-safe adhesive products on the market for you to choose from.<\/p>\n

 <\/p>\n

 <\/p>\n

What Are the Standards and Labels for Food-Safe Glue?<\/h2>\n

According to the FDA, any adhesive that comes in contact with food is classified as a food contact substance or FCS. These substances have to follow a particular set of regulations, which means that during the manufacturing of these adhesives, only certain ingredients can be used. Any deviation from this process means that the product cannot be labeled as a food-safe adhesive, which leaves the manufacturer in question liable for any harm caused by said products.<\/p>\n

\"Non-Compliant<\/p>\n

What are the labeling requirements for adhesives that are graded as food-safe though? Well, there are a few criteria that need to be met, this includes the label\u2019s face stock, the internal barcodes associated with the product, the ink used in the display of the nutritional information, as well as the dates and lot codes. All of these elements need to be presented in a manner that aligns with the FDA\u2019s standards in order for any adhesive to be considered food safe.<\/p>\n

\"Food-Safe<\/p>\n

The FDA goes even further by differentiating between direct and indirect contact substances. This is because, besides adhesives, things like ink can, directly and indirectly, come into contact with foodstuffs, and there are stringent regulations for substances in both categories. Things like labels and plastics are considered indirect contact substances, whereas things like the ink used to indicate the date of expiry on fruit would be considered a direct contact substance.<\/p>\n

\"Non-Toxic<\/p>\n

As you can imagine, this can be a lot of legwork for any company, and worse so, can leave smaller companies a bit confused thanks to the notoriously ambiguous wording set out in FDA guidelines. This leaves loads of room open for consumers to be deceived, as someone could follow their own interpretation of these guidelines, stick an FDA-approved sticker on their product, and sell it without anyone being the wiser.<\/p>\n

You should also note that the FDA does not approve or endorse any products. This means that anything with a fancy FDA-approved sticker could potentially be about as safe to consume as the plastic wrapping it comes in. Weird, right? In the FDA\u2019s defense, it is the responsibility of the manufacturers to ensure that the appropriate materials and processes are used in the manufacturing of their goods.<\/strong><\/span><\/p><\/blockquote>\n

 <\/p>\n

What Are Food Safe Adhesives Used For?<\/h2>\n

While in the crafting industry food-safe adhesives are used to adhere surfaces and\/or objects that will be used in contact with foodstuff, their applications can go far beyond this rudimentary usage. They are actually common in tons of industrial and food manufacturing environments to ensure that things processed there aren\u2019t contaminated by the surrounding machinery.<\/p>\n

\"Proximity<\/p>\n

A good example is how food-safe adhesives are used to bond mesh gauze on filters. These filters can be used to process a variety of liquid substances often in an attempt to purify them for consumption or packaging. These adhesives help to secure these filters not only by preventing them from shifting but by ensuring that the liquids being processed do not into contact with conventional adhesive products.<\/strong><\/span><\/p><\/blockquote>\n

\"Food-Safe<\/p>\n

Another common application for food-safe adhesives is on machines that dispense food for immediate consumption. One of these machines that you\u2019ve likely come across in your daily life is an ice-cream dispenser, which uses food-safe adhesives to create a seal around the internal dispenser recess in the interest of avoiding contamination by milk or ice that may have gotten stuck in these little nooks.<\/p>\n

\"Ice<\/p>\n

Let\u2019s have a look at how these adhesives might be used inside your home for a minute. Did you know that even your kitchen knives make use of food-safe adhesives? That\u2019s right, and while you might be thinking that the blades are made of stainless steel, so they don\u2019t need to be food-safe, the handles of your knives are not. The handles are typically sealed with a food-safe adhesive to prevent food particles from becoming stuck between the hilt and the plastic\/wooden cover of the handle.<\/p>\n

\"Glued<\/p>\n

Even the machines used to package your food have to make use of food-safe adhesives either as a bonding mechanism or as a protective layer. That\u2019s right, some of these adhesives as so strong and durable that you can coat a tool in them in order to make it conducive to working with foodstuffs. This does require that the function of the object not be impeded though, that\u2019s why stainless steel is used for kitchen knives and not normal steel covered in food-safe glue.<\/p>\n

Which Glues Are Considered Food Safe?<\/h2>\n

If you\u2019ve ever been to a craft or hardware store, then you know that there are loads of glue products on the market. However, you should know that there are only a few types of adhesives that are food safe once they have had a chance to cure completely. So, rather than you having to search through an insufferable number of websites to find out which glues are food safe, we thought we\u2019d list them right here for your convenience.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Two-Part Epoxy Glues<\/h3>\n

These days two-part epoxy resin glues are some of the most popular heavy-duty adhesives on the market. It also happens to be one of the strongest food-grade glue products on the face of the planet, with pretty much no exceptions aside from customer-made adhesives. This being said, epoxy glues don\u2019t exactly come cheap, but they\u2019re well worth it considering their adhesion strength and versatility.<\/p>\n

\"Cured<\/p>\n

What are two-part epoxy adhesives you ask? Epoxies are food-grade glue that (as the name suggests, come in two parts. These parts are the epoxy and the hardener respectively, and when combined create a thermal reaction that results in a pretty strong glue. Bonds formed through the use of epoxy glues are waterproof, fireproof, and impact resistant.<\/p>\n

Although pretty much any epoxy adhesive is food safe<\/a> when completely cured (which usually takes around 24 hours), only epoxies made following the FDA guidelines can be used in the manufacturing, transportation, and\/or packaging of foodstuff. This is why some cutting boards are made of epoxy resin, a chemical that is nearly identical to the aforementioned two-part adhesive<\/strong><\/span><\/p><\/blockquote>\n

 <\/p>\n

Best Epoxy Glue: GORILLA Two-Part Epoxy<\/h4>\n
