Why Does My Artificial Tree Smell Like Plastic When First Opened

Unboxing a new artificial Christmas tree should be a joyful moment—anticipation builds as you prepare for the holiday season, only to be met with an unexpected wave of chemical odor. That sharp, plasticky smell wafting from your freshly opened tree is more common than you might think. While it’s not usually dangerous, it can be unpleasant and even concerning for families with children or pets. Understanding the root cause of this odor, how long it lasts, and what you can do about it empowers you to enjoy a festive atmosphere without compromise.

The scent is not a defect, but rather a byproduct of manufacturing, materials, and storage. With proper handling and a few smart strategies, you can significantly reduce or completely eliminate the plastic smell in just days. This guide breaks down the science behind the odor, offers practical solutions, and shares real-world experiences from homeowners who’ve successfully refreshed their trees.

What Causes the Plastic Smell in New Artificial Trees?

Artificial Christmas trees are primarily made from polyvinyl chloride (PVC) or polyethylene (PE), both synthetic plastics derived from petroleum. During production, these materials are heated, molded, and shaped into needles, branches, and trunks. The process releases volatile organic compounds (VOCs)—gases emitted from certain solids or liquids that include chemicals like phthalates, benzene, and formaldehyde. These VOCs are responsible for the distinct “new plastic” smell.

Manufacturers often use flame retardants, stabilizers, and softening agents to meet safety standards and improve durability. While these additives serve functional purposes, they also contribute to off-gassing—the release of trapped gases after packaging. When your tree sits compressed in a box for months during shipping and retail display, these gases become concentrated. Once unboxed, they disperse into the air, creating the noticeable odor.

“Off-gassing from PVC-based products is common in household items like shower curtains, vinyl flooring, and yes—even artificial trees. Most emissions decrease significantly within the first 72 hours.” — Dr. Lena Torres, Environmental Health Scientist, University of Colorado

It's important to note that while short-term exposure to low levels of VOCs is generally not harmful for healthy adults, sensitive individuals may experience headaches, dizziness, or respiratory irritation. Pregnant women, infants, and those with asthma or chemical sensitivities should take extra precautions.

How Long Does the Plastic Smell Last?

The duration of the plastic odor depends on several factors: ventilation, room temperature, tree size, and material composition. In most cases, the smell begins to fade within 24 to 72 hours when the tree is placed in a well-ventilated area. However, heavier trees with dense foliage or those stored in sealed packaging for extended periods may retain odors for up to two weeks.

Higher temperatures accelerate off-gassing, so placing your tree near a heat source (like a radiator or sunny window) can help—but avoid direct sunlight, which may degrade plastic over time. Conversely, cold environments slow down the release of VOCs, meaning a tree unpacked in a chilly garage will take longer to air out.

Tip: Unpack your artificial tree at least 3–5 days before decorating, especially if you're sensitive to smells or plan to place it in a small space like a bedroom or office.

Step-by-Step Guide to Remove the Plastic Smell

Eliminating the odor doesn’t require expensive products or complicated methods. Follow this timeline-based approach to safely and effectively freshen your tree:

1. Day 1: Unbox in a Ventilated Area
   Open the tree outside, in a garage, or near an open window. Let it sit for at least 4–6 hours. Do not bring it indoors immediately.
2. Day 1–2: Use Fans for Airflow
   Set up oscillating fans around the tree to circulate air. This speeds up VOC dispersion. Avoid using heaters directly on the tree, as excessive heat may warp plastic components.
3. Day 2: Wipe Down Branches
   Mix a solution of equal parts water and white vinegar in a spray bottle. Lightly mist a microfiber cloth (not the tree directly) and gently wipe PVC branches. Vinegar neutralizes odors and removes residual manufacturing oils.
4. Day 3: Activate Odor Absorbers
   Place activated charcoal bags, baking soda boxes, or odor-absorbing gels near the base of the tree. These materials trap lingering molecules. Replace or recharge every 48 hours.
5. Day 4–5: Introduce Natural Fragrance (Optional)
   If the plastic smell is nearly gone, add subtle seasonal scents using essential oil diffusers (e.g., pine, cinnamon, or orange). Do not spray oils directly on the tree—this may damage plastic or attract dust.

By following this sequence, most users report a dramatic improvement within five days. For persistent odors, repeat the wiping and airing steps before decorating.

Do’s and Don’ts When Dealing With Tree Odors

Do’s	Don’ts
Unpack the tree outdoors or in a garage first	Bring the tree straight into your living room without airing
Use fans to increase airflow	Use bleach or ammonia-based cleaners on branches
Clean branches with diluted vinegar or mild soap	Apply aerosol sprays or perfumes directly to the tree
Store the tree in breathable bags after use	Compress the tree tightly in plastic storage containers
Test cleaning solutions on a small section first	Expose the tree to open flames or high-heat lights

Following best practices ensures not only odor control but also extends the life of your tree. Improper cleaning or storage can trap odors and create mold or mildew issues in future seasons.

Real Example: How One Family Reduced Odor Before Christmas Eve

The Ramirez family in Portland, Oregon, purchased a 7.5-foot pre-lit artificial tree online in early December. Upon opening, they were hit with a strong chemical smell that lingered in their apartment hallway. Concerned because their toddler had asthma, they decided not to set it up in the living room immediately.

They followed a modified version of the step-by-step guide above: they assembled the tree in their detached garage, ran two box fans facing it for 12 hours a day, and wiped each branch tier with a vinegar-dampened cloth. They also placed bowls of baking soda around the base overnight.

After three days, the odor was barely detectable. They moved the tree inside, decorated it, and enjoyed a fragrance-free holiday celebration. “We were skeptical at first,” said Maria Ramirez, “but giving it time and airflow made all the difference. Our son didn’t have any breathing issues, and our guests didn’t notice any weird smells.”

Tips for Preventing Odors in Future Seasons

Even if your current tree has lost its plastic scent, proper care after the holidays prevents odors from returning next year. Many people unknowingly re-trap VOCs by storing trees improperly.

• Always disassemble and clean the tree before storage. Dust and debris can mix with residual chemicals and produce musty or plastic-like smells over time.
• Use fabric storage bags instead of sealed plastic covers. Breathable materials prevent moisture buildup and allow any remaining gases to escape gradually.
• Store in a cool, dry place—avoid attics or basements with high humidity, which can degrade plastic and promote off-gassing when reopened.
• Label your storage container with the date and any notes (e.g., “cleaned Dec 2024”) to track maintenance.

Tip: Place cedar blocks or silica gel packets inside the storage bag to deter pests and absorb moisture—just keep them away from direct contact with the tree.

Frequently Asked Questions

Is the plastic smell from artificial trees toxic?

Most modern artificial trees sold in North America comply with consumer safety regulations (such as CPSIA and Prop 65 in California). The levels of VOCs released are typically low and not considered hazardous for short-term exposure. However, prolonged inhalation in poorly ventilated spaces may irritate sensitive individuals. If you experience symptoms like headaches or nausea, increase ventilation or temporarily remove the tree from the area.

Can I wash my artificial tree to remove the smell?

No—submerging or hosing down an artificial tree can damage wiring (especially in pre-lit models), warp plastic branches, and promote mold growth. Instead, spot-clean with a damp cloth and natural cleaning solution. Never put any part of the tree in a washing machine or dishwasher.

Are there artificial trees that don’t smell like plastic?

Yes. Some premium brands use low-VOC materials or alternative plastics like PE (polyethylene), which tends to have a milder odor than traditional PVC. Look for trees labeled “low-emission,” “phthalate-free,” or “eco-conscious.” While often more expensive, these options are ideal for households with allergies or environmental concerns.
