Technologies
Polycad is at the cutting edge of plastic packaging technologies for the food, toiletries, and detergent industries. With a wide range of advanced production and decoration technologies, the use of diverse raw materials—including post-consumer recycled (PCR) and biodegradable options—and creative thinking, Polycad offers products for additional industries such as hydroponic growing trays, ink cartridges for digital or 3D printers, lab testing solutions, and much more.
HDPE/PP
EXTRUSION BLOW MOLDING
This process is used to produce containers of up to 5 liters with integrated carrying handles. This method allows Polycad to design and manufacture bottles and containers with a high level of complexity, different neck sizes and shapes, including integrated handle designs, ranging from volumes of 500 cc to 5000 cc. Usage of HDPE/PP allows hot filling and more aggressive content such as chemical liquids and disinfection agents.
Products manufactured with this technology include between others: containers for sauces for the food professional market, 2-3 litters milk and yogurt containers, tahini jars, containers for disinfection agents and detergents, sprayers, and more.
The materials used in this process are high-density polyethylene (HDPE) and polypropylene (PP), both of which are highly resistant to chemicals. The products can be colored in an unlimited variety of shades.
The production process includes three stages:
- Extrusion – Converting the raw material, which arrives as pellets, into a flexible sleeve suitable for shaping it into the container design.
- Blow Molding – Inflating and shaping the sleeve inside a mold using compressed air injected through a blow pin, to form the final product. At this stage, IML/BML labeling can be applied.
- Trimming – Removing the molded product from the mold and trimming excess material.
This technology is used to produce highly transparent products (glass-like appearance) that are also resistant to gas transmission. It is ideal for manufacturing items such as: clear food packaging jars (for chocolate spread, mayonnaise, mastered, cheese), squeezable bottles (for tahini, honey, sauces and olive oil), small size milk bottles and bottles and jars for toiletries (shampoo, conditioner, body wash), among others.
The material used in this process is PET, a type of polyester that provides strength and clarity, and can be colored in a wide variety of shades without limitation.
The production process includes three main stages:
- Injection of PET – After melting, the PET is injected into a screw barrel inside a mold, creating a tube with a threaded neck (known as a preform).
- Stretch Blow Molding – The preform is stretched and inflated inside a dedicated mold using compressed air, forming the final shape of the product.
- Product Ejection – The finished product is removed from the mold by a robot.
- Shrink sleeve – a decorative sleeve is applied to the bottle by steam which shrinks it onto the bottle or a jar.
PET- Injection
Stretch Blow Molding
In this process, we produce containers, jars, caps, closures and lids for various types of packaging. Some of these products include safety mechanism, such as tamper-evident closures, to ensure the product hasn’t been opened prior to reaching out the end consumer.
The materials commonly used in this production method are polypropylene (PP) and low-density polyethylene (LDPE), both of which can be colored in an unlimited variety of shades.
The injection molding process includes two main stages:
- Injection – The melted material is injected via a screw barrel into a mold cavity that shapes the product. At this stage, IML labeling can be applied.
- Ejection – The finished product is removed from the mold by a robot.
What sets Polycad’s injection molding apart is our ability to create thin-walled, food-grade packaging with labels that are injected directly into the mold during production—making them inseparable from the product. This is known as IML (In-Mold Labeling).
