Open shelves in the refrigerator are a source of constant problems: drops from defrosting, odors from neighboring products, accidental leaks of packages. Even in modern models with the system No Frost moisture and condensation inevitably accumulate, and plastic surfaces absorb the aromas of fish, spices or cheeses over time. Closed shelves solve these problems, but not every material is suitable for a refrigerator.
In this article we will examine 10 proven methods closed shelves - from budget (cling film, parchment) to professional (silicone mats, acrylic inserts). We'll tell you which materials safe for productsand which can cause mold or a chemical taste. We will separately dwell on mistakeswhich 90% of users make, and give a checklist for caring for closed shelves.
Spoiler: There is no ideal universal solution - the choice depends on the type of refrigerator (drip, No Frost, Low Frost), frequency of cleaning, and even on whether you store liquid foods (soups, sauces) on the shelves. But after reading, you will definitely be able to choose an option that will extend the life of your refrigerator and keep food fresh.
Why do you even need to close the shelves in the refrigerator?
At first glance, closed shelves are about aesthetics and convenience. But in fact, we are talking about four key problemsthat they solve:
- 💧 Condensation and moisture. Even in refrigerators No Frost frost forms on the back wall, and when the door is opened, warm air condenses on the shelves. The closed cover prevents the accumulation of water under the products.
- 🦠 Bacteria and mold. Open plastic is porous - food debris accumulates in microcracks, which become a breeding ground for microbes. Smooth coatings (silicone, acrylic) are easier to disinfect.
- 👃 Transmission of odors. Fish, onions, cheeses - their aromas are absorbed into plastic and transferred to other products. A barrier layer (for example, glass) blocks this diffusion.
- 🧊 Frozen food. In the freezer or on the top shelves of the refrigerator, food can freeze to open plastic. Closed surfaces reduce the contact area. drip system food may freeze to exposed plastic. Closed surfaces reduce the contact area.
Research German Society for Nutrition (DGE) has shown that in refrigerators without shelf protection, the number of bacteria on surfaces is 3 times higher than in those that use removable covers. At the same time the most dangerous zones are the lower shelves (under meat products) and the bottom of drawers for vegetableswhere up to 70% of all contaminants accumulate.
But there is also a downside: incorrectly selected the material may make problems worse. For example, fabric napkins absorb moisture and become a breeding ground for mold, and aluminum foil oxidize and give products a metallic taste. Next is a detailed analysis of each option.
Top 5 materials for closing shelves: pros and cons
We tested popular solutions according to three criteria: safety for products, ease of care i durability. The results are in the table below.
| Material | Pros | Cons | Service life | Price (for 1 shelf) |
|---|---|---|---|---|
| Silicone mats | Hypoallergenic, do not absorb odors, dishwasher safe, not slip | Expensive, can be deformed at high temperatures (if washed with boiling water) | 3–5 years | from 500 ₽ |
| Cling film | Cheap, easy to replace, transparent | Tears, sticks to products, requires frequent replacement | 1–2 weeks | from 20 ₽ |
| Parchment paper | Eco-friendly, breathable, suitable for baking | Absorbs moisture, tears quickly, not suitable for liquid products | 3–7 days | from 15 ₽ |
| Glass inserts | Do not absorb odors, easy to clean, durable | Heavy, can break, expensive | 10+ years | from 1,200 ₽ |
| Acrylic sheets | Lightweight, scratch-resistant, can be cut to size | May turn yellow over time, not all types are food grade | 5–7 years | from 800 ₽ |
Life hack: if you choose between silicone and acrylic, pay attention to certification. Food grade silicone must be marked LFGB or FDA, and acrylic must be marked food grade. Without these designations, the material may release harmful substances when in contact with fats or acids (for example, from lemons or marinades).
⚠️ Attention: Do not use plastic bags to cover shelves! At low temperatures they become brittle and crumble into microparticles that can get into food. In addition, cheap polyethylene releases carcinogens upon contact with fatty products.
Budget solutions: cling film, parchment, foil
If you need to quickly and cheaply close shelves, these three options will save you situation. But everyone has pitfalls.
1. Cling film (stretch)
The most popular way is to stretch the film onto the shelf, securing the edges with tape or rubber bands. Suitable for:
- 🍗 Storing meat/fish (prevents leaks)
- 🧀 Cheeses and sausages (blocks the spread of odor)
- 🥛 Bottles and cans (protects against condensation)
How to use correctly:
- Cut a piece of film with a margin of 5-7 cm at the edges.
- Put it on the shelf, smoothing out air bubbles.
- Secure the edges with masking tape (not ordinary tape - it leaves glue!).
- Change the film every 3-5 days or after contact with juices/fats.
Cons:
- ❌ Sticks to food when frozen (in the freezer).
- ❌ Poor air permeability - under the film it can condensation accumulates.
- ❌ Cheap film breaks due to weight (for example, under jars of pickles).
2. Parchment paper
Ideal for dry products: bread, fruits, vegetables. Pros:
- 🌿 Eco-friendly and biodegradable.
- 🔥 Withstands temperatures from -40°C to +220°C.
- 🚫 Does not stick to products.
But it is not suitable for liquids - the paper gets wet and tears. The best option: combine with a silicone mat (parchment on top, silicone on the bottom).
3. Aluminum foil
Foil reflects cold and prevents icing, but has critical disadvantages:
- ⚠️ Oxidizes upon contact with salt/acids (for example, from pickled cucumbers).
- ⚠️ May impart a metallic taste products.
- ⚠️ Tears at the folds, forming sharp edges.
If you still use foil:
- 🔹 Cover it on top with parchment.
- 🔹 Do not store sour or salty foods on it products.
- 🔹 Change every 2-3 days.
Check the food labeling
Secure the edges so that the material does not move out
Change the coating at least once a week
Do not use near heating elements (in the No Frost zone)-->
Professional solutions: silicone, glass, acrylic
If you are willing to invest in durable materials, these three options will last for years and make caring for your refrigerator easier.
1. Silicone mats
Leader in price/quality ratio. The best models:
- 🟢 OXO Good Grips —with sides, do not slip, can be cut with a knife.
- 🟢 SimpleHouseware —thin, suitable for the freezer.
- 🟢 Kitchen + Home —with antibacterial coating.
How to choose the size:
- Measure the shelf with a margin of 1-2 cm along the edges.
- For the freezer, take thick mats 3–5 mm (thin ones crack in the cold).
- For the freshness zone (0°C), perforated models for air circulation are suitable.
Care:
- 🧼 Wash in warm water with soda (1 tbsp. spoon per liter).
- 🚫 Do not use abrasive sponges - silicone is scratched.
- 🔄 Once a month, disinfect with vinegar solution (1:1 with water).
2. Glass inserts
Expensive, but reliable. Suitable for:
- 🍷 Storing bottles (do not slip).
- 🥩 Semi-finished meat products (easily washed off fat).
- 🧊 Freezers (do not deform in the cold).
Important:
- 🔹 Use tempered glass at least 4 mm thick.
- 🔹 Check that the edges are polished (no sharp edges) edges).
- 🔹 Place silicone pads under the glass so as not to scratch the plastic of the refrigerator.
⚠️ Attention: Not all refrigerators are designed for the additional weight of glass! In models with plastic guides (for example, Indesit BIAA 13 or ATLANT MXM 1705) the shelves may sag. Before purchasing, check the maximum load in the instructions.
3. Acrylic sheets
A lightweight alternative to glass. Pros:
- 🔹 2 times lighter than glass with the same strength.
- 🔹 Can be cut with a hacksaw to any size.
- 🔹 Does not break, resistant to impacts.
Cons:
- ❌ Over time it turns yellow (especially cheap acrylic).
- ❌ Scratches from knives and forks.
- ❌ Not all types are food grade - check the certificate!
Where to buy:
- 🛒 In construction stores (for example, Leroy Merlin) - sheets 3-5 mm thick.
- 🛒 On AliExpress - ready-made sets for refrigerators (search by request
fridge shelf cover acrylic).
How to cut acrylic at home
1. Mark the sheet with a marker.
2. Saw with a hacksaw (fine teeth!).
3. Sand the edges with sandpaper (grain size). 400–600).
4. Wash with soap to remove dust.
What not to do when closing shelves
Even the safest material can be harmful if used incorrectly. Here are 5 common ones. errors:
- Use household tape for fixation. The adhesive from the tape is absorbed into the plastic and then cannot be washed off. Replace with painting tape or silicone clothespins.
- Close the ventilation holes. In refrigerators No Frost the air circulates through the cracks in the back wall. If you close them, the temperature will rise by 2-3°C.
- Place heavy objects on fragile surfaces.For example, jars with pickles on parchment or glass containers. silicone.
- Use materials with a printed pattern. Paint may contain lead or other toxins that migrate into the products.
- Do not wash the coating before the first installationOn new silicone mats or. glass often leaves traces of production (oils, dust).
Another important point: do not mix materials on one shelf, for example, if you place parchment on a silicone mat and foil on top, condensation will accumulate between the layers, which will cause will lead to mold. It is better to choose one solution and stick to it.
How to care for closed ones. shelves?
Closed shelves require less frequent cleaningbut still need regular maintenance. Optimal schedule:
| Coating type | Cleaning | Disinfection | Replacement |
|---|---|---|---|
| Silicone mats | Once every 2 weeks (with soap) | Once a month (with vinegar) | Once every 3–5 years |
| Cling film | Every 3–5 days | Not required | Every wash |
| Glass inserts | Once a month (glass cleaner) | Once every 3 months (alcohol solution) | In case of damage |
| Acrylic sheets | Once every 3 weeks (soft sponge) | Once every 2 months (baking soda) | When yellowing |
Washing instructions:
- Remove the coating and rinse in warm water with baking soda (1 tablespoon per liter).
- For disinfection, use acetic solution (1:1) or hydrogen peroxide (3%).
- Dry thoroughly before installation - moisture under the coating leads to mold.
- For glass and acrylic, use microfiber ragto avoid streaks.
⚠️ Attention: Never wash silicone mats in the dishwasher at temperatures above 60°C! This will lead to deformation and loss of elasticity. The optimal mode is 40–50°C.
Alternative methods: trays, containers, magnetic coatings. data-i="286">If standard solutions are not suitable, consider these unusual options:
If standard solutions aren't an option, consider these unusual options:
- 📦 Plastic trays with sides. Suitable for storing meat, fish, vegetables. The best models: IKEA 365+ or Tupperware FridgeSmart. Minus - they take up a lot of space.
- 🧲 Magnetic coatings. Attached to metal shelves (for example, in refrigerators Samsung RB30J3000). Plus: they do not move when the door is opened.
- 🧺 Bamboo matsEco-friendly, but absorb moisture - suitable only for dry ones. products (cheeses, sausages).
- 🧊 Ice traysCan be used as stands for jars or bottles to prevent leaks.
For the freezer, the best option is silicone baking dishes (for example Silicomart). They can withstand temperatures down to -40°C and do not crack when liquids freeze.
FAQ: Frequently asked questions about closing shelves in the refrigerator
Is it possible to use regular paper (newspaper, office paper) instead of parchment?
No! Printing ink contains lead and other heavy metals that can migrate into products. In addition, regular ink. paper quickly gets wet and becomes a source of bacteria. If you don’t have parchment, it’s better to take paper towels without a pattern - they are safer.
How to secure a silicone mat so that it does not move?
There are 3 reliable way:
- Use silicone glue (food grade, for example, Dow Corning 732) - apply pointwise in the corners.
- Secure plastic clothespins (sold in sewing departments).
- Place under the rug anti-slip backing (for example, for carpets).
Do not use double-sided tape - it leaves sticky marks that cannot be washed off.
Is it true that closed shelves increase energy consumption?
Yes, but only slightly. Closed coatings (especially thick ones like glass or acrylic) can slow down air circulation in refrigerators No Frostcause the compressor to run 5-10% longer. However, the difference in the electricity bill will be only 10–20 rubles per month. If this worries you, choose perforated silicone mats or mesh trays.
What to do if mold appears under the coating?
Urgently remove the material and treat the shelf:
- Wipe vinegar solution (undiluted).
- Apply food grade soda for 10 minutes, then rinse.
- Dry the shelf with a hairdryer (cold air!).
- Before installing a new coating, treat the surface spray with silver ions (for example, Silver Care).
If mold has appeared on a silicone mat, it is better to throw it away - the pores of silicone are deep, and it is impossible to completely remove the fungus.
Is microwave cling film suitable for covering shelves?
Yes, but with reservations:
- ✅ Suitable for short-term use (up to 3 days).
- ❌ Cannot be used in the freezer - at low temperatures the film becomes fragile.
- ❌ Not suitable for storage hot products (for example, soup in a pan) - may melt.
It is better to choose a special one refrigerator film (for example, Glad Press'n Seal) - it is thicker and does not tear when in contact with moisture.
