It’s time again! The most magical season of the year has arrived, and Christmas Day is drawing near. It's time to take the decorations out of the boxes and deck the halls! Where should you start? Naturally, with the tree, which will brighten up your living room all December long (and maybe even until Easter if you forget to put it away again this year!). While searching for the assembly instructions, you might wonder: how are artificial Christmas trees made? What materials are artificial Christmas trees made of? Are they harmful to the environment? These are common questions, especially when you notice all that plastic… But, synthetic trees are an excellent alternative to real ones, and their production process is really fascinating!

The Role of Masterbatches in Artificial Christmas Tree Production

First, we need to distinguish between the two main methods used to create the branches of artificial Christmas trees: plastic extrusion and injection molding. In both cases, the selected polymer resin (usually PVC or PE) is added with coloring masterbatches. When mixed with the plastic, these masterbatches give the trees their characteristic green and brown colors. In addition to coloring pigments, masterbatch formulas can include other additives that provide unique properties. For instance, UV-resistant additives for outdoor artificial Christmas trees ensure greater durability and color stability to sunlight exposure. Flame retardants or antimicrobial additives can be an additional guarantee of safety for domestic environments. An anti-static additive can also help prevent dust accumulation.

Artificial Christmas Tree Production: Extrusion Method

As mentioned earlier, there are two main methods for producing artificial Christmas trees. The most common is the extrusion method, a process similar to that used for creating synthetic grass. The process begins with a PVC compound that is heated and extruded into continuous sheets, forming a large roll. This roll is then cut into long, thin strips. Then, these strips are transported into a machine that cuts small incisions along one edge, simulating pine needles. At this point, the incised PVC strips are twisted together with a metallic wire to provide shape and rigidity. The assembled piece is then cut to the desired length. This method produces artificial Christmas trees with branches featuring “soft” needles. While practical and durable, they are less realistic in appearance compared to other methods.

Artificial Christmas Tree Production: Injection Method

The second method for producing artificial Christmas trees is injection molding, which creates branches that look and feel similar to a real tree. However, this process is more complex and, consequently, tends to be more expensive. In this case, polyethylene (PE) is used as the resin. Once a compound is created with masterbatch and/or pigments and additives, the plastic is heated to a high temperature until it melts. It is then injected into molds that precisely replicate the shape of pine needles. After cooling, the branches are collected and assembled with metallic wire, after a thorough quality check. To optimize production costs while maintaining a good aesthetic result, branches made of PVC and PE are often combined. PVC branches are placed internally to create volume, while PE branches are positioned externally to provide a more visually pleasant and natural look.

Additional Features of Artificial Christmas Trees

At this point, the branches are ready to be attached to the central structure. The most common artificial Christmas trees on the market use a hook-on branch system, where branches are “hooked” directly into designated slots on the trunk. There are also trees with an umbrella-like opening and those already pre-assembled, for which it is sufficient to lower and open the branches. Other components of the synthetic tree include the pedestal, typically made of metal, and the central structure - representing the trunk of the tree - which can also be made of a metal bar, or a PVC plastic tube pigmented green or brown. Additionally, the tree can be completed with lights, or a sprinkle of fake snow, usually made with synthetic fiber spray.

Are Artificial Christmas Trees a Sustainable Choice?

Is the production of artificial Christmas trees sustainable? It turns out that artificial trees can be a valid substitute for real trees, even though they are made of non-biodegradable plastic. Indeed, an artificial Christmas tree can be used for over ten years (when you think about it, 10 Christmases aren’t that many!). This makes it a more sustainable choice compared to cutting down live trees or uprooting them to place in a pot, outside their natural habitat. Furthermore, many artificial Christmas tree manufacturers, driven by current market demands, are opting to use recycled and bio-based plastics. Therefore, if chosen and used over a long period, an artificial tree can be an effective way to help preserve natural resources.
