Use of products

Petit plastic molds are ready-to-use molds, single-use and therefore disposable after use.
However, it is possible to reuse some models after careful washing, drying and storage.
PETIT has published an advice guide on the reuse of its plastic moulds . Read it carefully.
Attention :
. PETIT cannot be held responsible in the event of a problem resulting from the reuse of its moulds.
. Molds cannot be machine washed.

  • A perfect finish
    Traditional pastry circles require finishing the top with a spatula and do not allow a perfect finish, unlike plastic molds which make it possible to obtain a smooth and flawless surface from the mold.

  • Economic
    To produce pastries in series, plastic molds are economical, unlike silicone or stainless steel molds, which are expensive, sometimes difficult to clean, and which must be in stock in quantity to be able to make large productions. Plastic molds are up to 10 times cheaper than stainless steel frames or silicone molds

  • Time saving
    Disposable plastic molds save time in production: no need to wash them carefully and re-pack them to store them away from humidity.

  • Space saving
    After seasonal productions (eg end-of-year logs), you free up storage space by not keeping the molds used.

  • Freezing resistance
    Placed under negative cold, the thermoformed molds retain their mechanical properties and do not deform under the effect of the cold.

The molds fitted with skirts (a reinforcement that acts as a base), once filled and frozen, are designed to receive lukewarm water in the lower part: it allows the cake to be unmolded more quickly, while keeping its shape intact.
Molds without a skirt are designed with a draft: their edges are not quite straight, but slightly inclined to facilitate the sliding of the cake during unmolding.

In order to optimize the conservation of plastic molds, follow these few simple tips to optimize the life of your products:

  • Keep the molds in a place protected from heat, humidity and direct sunlight. It is best to store them in the cover and box in which they were delivered to you.

  • Store the molds away from flammable materials or heat sources (they are made of plastic and can therefore deform or melt under the effect of heat).

It is recommended to use the molds within one year of their delivery. Note that it is essential to store them away from heat, humidity and dust, and to keep them in the food bag in which they are delivered.

The choice of mold size depends on several factors, such as the number of servings you want to make and the type of dessert you are preparing. Check product descriptions for specific sizes and choose the one that best suits your recipe.

Yes, but our plastic molds are not designed to be used when baking. The thermoformed plastic used in our molds has a maximum resistance which can vary between +60°C and +80°C. It is therefore important not to expose them to high temperatures beyond their resistance limits, as this could cause the material to warp or melt.

Present on the molds with skirts (log molds and frames in particular), these are geometric patterns that bring relief to the surface of the thermoformed plastic. The gadroons are used to improve the mechanical resistance of the mould: they give them better stability, which is essential especially during the assembly and storage stages of your cakes. Thanks to them, the mold does not deform and remains perfectly in place.

Some of the dessert molds have a very straight undercut (vertical part of the cake) to give beautiful desserts. Also after setting in the cold, it can be difficult to unmold them, simply by turning them over. On some moulds, pre-cut "ears" are present: they allow the mold to be torn to obtain an impeccable dessert finish.
The edges of the entremets are thus very neat, the bottom (= the top once unmolded) is perfectly flat and smooth, which allows a perfect icing; unlike cakes made with classic pastry circles, which require refining the top with a spatula, which makes a less regular finish.


Thermoforming is the industrial technique that consists of taking a sheet of plastic to give it a certain shape thanks to an imprint, by heating it to the desired temperature. As it cools, it hardens, retaining the shape of the desired mould. The advantage of thermoformed molds is that they have good rigidity during filling, but also a certain flexibility for clean and precise demoulding. Thermoformed packaging can be created from recycled materials and are, for those made of APET, recyclable.

Thermoformed plastic molds offer several advantages over other molding techniques. Here are some of the main benefits:

  • Cost: Thermoformed plastic molds are generally less expensive to produce than molds made with other molding techniques, such as injection or blow molding. This makes thermoforming more affordable, especially for small production runs.

  • Design flexibility: Thermoforming allows the realization of complex shapes, fine details and varied geometries. Thermoformed plastic molds can be adapted to fit different shapes and sizes of parts.

  • Speed: The thermoforming process is often faster than other molding techniques, allowing for shorter production times. It can be used for the manufacture of rapid prototypes or to meet urgent production requests.

  • Lightness: Products made with thermoformed plastic molds are generally lighter than those obtained by other molding methods, which can be advantageous in many applications, especially to reduce transport costs or related musculoskeletal disorders to repeated handling.

  • Customization: Thermoforming offers the possibility of easily customizing parts using different plastic materials, thicknesses or surface finishes. This makes it possible to meet specific customer requirements and achieve attractive end products.

  • Material saving: The thermoforming process allows the use of plastic sheets, which reduces material waste compared to other molding techniques that require massive molds. This can result in significant material savings.

PETIT uses 3 distinct raw materials to make its moulds:

  • APET, more commonly known as PET, is based on amorphous polyethylene terephthalate. They are used to make packaging through a thermal molding process. Transparency, recyclability, low price, excellent mechanical properties, food-grade, it is THE most common plastic for the manufacture of food containers, especially for water bottles. The APET molds manufactured by PETIT are made from thicknesses ranging from 200 microns (=0.2 mm) to 900 microns maximum.

  • PS (polystyrene) is a transparent thermoplastic with an amorphous structure. It is particularly used for disposable tableware, decorative elements, economical boxing, etc. It has better rigidity, and is also economical. PETIT uses PS films whose thicknesses range from 1.2 to 2mm depending on the shape of the molds and the rigidity necessary for the good performance of the cake during assembly and cold storage.

  • PVC or polyvinyl chloride: it is also interesting for its price and the fact that it can tear. PETIT round dessert molds are tearable to allow perfect unmolding of the cake. PETIT uses films from 0.2 to 0.9mm to manufacture its PVC moulds.

The minimum width of the width (plastic film) is 35 cm, and a maximum of 76 cm, which makes it possible to manufacture molds or trays in large format.


Since 1973, PETIT has been manufacturing all of its production of thermoformed molds in its factory located in France, at Les Échelles (Savoie), which specializes in the thermoforming of standard and custom-made food packaging. The raw materials are sourced exclusively in Europe, and meet the requirements related to the manufacture of products subject to hygiene and food safety.

We source our raw materials in France and, if necessary, in other countries of the European Union. Our molds are made in particular from recycled plastic. Of course, these are food-grade plastics that fully comply with current standards.

Our internal design office is at your disposal to consider the creation of a custom-made pastry mold or any other product manufactured using the thermoforming process (wedge, box, blister, etc.). You can contact us by phone at, Monday to Friday, 8 a.m. to 12 p.m. and 2 p.m. to 6 p.m.

Product information

They are adapted to the shapes of the frame moulds: placed at the bottom of the mould, they bring relief to the pastry. The structure sheets can also be cut to the desired shape to fit in a round entremets, at the bottom of a log mold or other.

Plastic recycling supply chains are becoming better organized. Our molds are made with material that contains up to 70% recycled material and can for the most part be recycled again after use. Also note that our molds are 100% French-made, which affects the carbon impact of the finished product. A reusable mold made in China does not have this advantage.

Of course. If you hesitate between several models, send us a request for samples to the address: orders@societe-petit.fr. We will be happy to direct you to the products that suit you best and we will offer you some samples. You will need to prove your professional status and send us your SIRET number.

Our thermoformed plastic molds are fully compatible with your cold rooms, in positive cold or negative cold.


Unlike the cardboard in which the molds travel, the cover is a container suitable for food contact. The molds are made in the factory according to the guidelines and precautions required to ensure food safety. In order to guarantee this safety, they are, as soon as they leave the production line, packed in these protective covers.
These covers are made of HDPE (High Density Polyethylene) and therefore 100% recyclable via the appropriate sorting channels.

The molds are manufactured in accordance with the food hygiene rules in force, so it is not necessary to wash the molds before their first use.

  • -10° to +80° for PVC molds (all round dessert moulds)

  • -30° to +60° for APET molds (all other moulds)
    Be sure to follow these instructions when making, storing and removing pastry from the moulds, so as not to alter the mechanical strength and quality of your moulds.

For the moment, we are only able to send orders to professional pastry chefs (CHR, bakeries, collective catering establishments, pastry training centers, etc.). We are an industrial manufacturer and wholesaler of disposable molds and only offer packaging suitable for professional use.


The material and color of the molds make it possible to maintain transparency, to assess and better manage the thickness of the different layers, and any lack of filling. The blue material also reinforces the safety of food manufacturing processes while meeting the requirements of international regulations for parts in contact with food. Blue plastics are now widely used in the food industry thanks to their visibility and quick identification on production lines (there is no blue food), in the event that foreign bodies fall into a food eating.

The skirt is present on the yule log molds or the frames, in addition to the fact that it ensures the stability and a good hold of the shape of the mold when it is filled, allows, once the frozen product to be poured into it lukewarm water for quick and clean release.

Some molds (log molds, frames) have a “remain”: their shape is slightly flared from bottom to top, so that once inverted, the cake comes out of the mold perfectly and slides naturally on the walls. This allows a perfect and clean release.

All our round dessert molds are equipped with ears with a pre-cut. These molds have a very low draft (vertical slope) to allow you to make a perfectly straight entremets, with sharp angles and a very flat and smooth bottom which allows for perfect icing. The ears are present to allow you to tear the mold to obtain this result, which a simple demoulding does not allow.
Only our dessert molds are easily tearable.

The expressions "PM" and "GM" translate to Small Model and Large Model, in general these terms are attributed to products that include two or more different sizes of the same model.
