Что такое пакетик? Полное руководство по упаковке саше & Разливочные машины

If you work in packaging, pharmaceuticals, еда, or cosmetics — or you’re a procurement engineer or machinery specialist — you’ve probably heard the term sachet. But what exactly is a sachet, and why do so many manufacturers and brands still rely on it? В этой статье, we’ll walk you through what is a sachet, how it’s used across industries, the advantages it offers, and how modern sachet filling/packing machines streamline production. The goal is to help you decide when sachet packaging makes sense for your product line.

Что такое пакетик? (Определение & Ключевые функции)

А пакетик is a small, sealed pouch used to hold a single portion of product. Commonly made of multi-layer film (пластик, фольга, or paper), a sachet is folded and sealed on three or four sides to create a tiny package. The name comes from the French word пакетик meaning “small bag”. Sachets are lightweight and portable, shielding their contents from air and moisture. Think of the ketchup packet next to your fries or the sugar portion for your coffee – those are sachets. You’ll find sachets in foods (spices, приправы, растворимый кофе), personal care (шампунь, кремы, wipes), and pharmaceuticals (single-dose medications or ointments). By providing a hygienic, single-use serving, sachet packs make it easy to transport and use products on the go.

Types of Sachets

Sachets come in several styles to suit different products and uses. Common formats include:

• Flat Sachets (4-side seal): The most common sachet style. It has four sealed edges and a flat profile, ideal for dry powders and thin liquids. You’ll see these used for single-use condiments, растворимый кофе, detergent samples, and small medical creams. They are space-efficient and cost-effective for low-volume portions.
• Stand-Up (Gusseted) Саше: These have a folded bottom (gusset) so they can stand upright on a shelf. The extra space makes them suitable for snacks, соусы, and juices. Stand-up sachets give products better shelf presence.
• Zip-Lock (Resealable) Саше: Equipped with a plastic zipper or reclosable seal. They allow consumers to open and close the pack multiple times. These are popular for vitamins, добавки, косметика (face masks or creams), or any product where the user needs to use part of the contents and save the rest.
• Medical/Pharma Sachets: Made with sterilized, high-barrier materials. These sachets are designed for pills, таблетки, мази, or sterile creams. They often meet strict pharmaceutical standards for safety and shelf-life.
• Pillow Sachets: (Sometimes just called pillow packs.) While not listed in all references, pillow sachets are formed from a continuous tube of material with sealed ends, giving a “pillow” shape. They’re very common for gel or liquid products (например. образцы шампуня, соусы, liquid medications) because the rounded shape holds more volume and is easy to squeeze out.

Each style is engineered for certain contents. Например, плоский sachets maximize printed area for branding, while pillow sachets handle extra liquid volume. Modern packaging lines can adjust the machine settings to produce any of these sachet types efficiently.

Why Choose Sachet Packaging?

Sachets offer several advantages that make them a smart choice for many products and markets:

• Портативность & Удобство: Sachets are tiny and lightweight, so they fit easily in pockets, кошельки, or travel kits. This portability makes single-use items very convenient for consumers on the go.
• Freshness & Защита: Sachets use hermetic seals that are airtight. This preserves the product’s freshness and prevents contamination or spoilage. A well-sealed sachet can greatly extend the shelf life of products like spices, приправы, or medical powders.
• Экономическая эффективность: Because sachets hold very small portions, they use less packaging material overall and reduce waste. In production, sachets require less film than larger packages, cutting material costs. They also save on shipping and storage costs per single dose. Single-dose sachets also help minimize product waste since you only open what you need.
• Precise Portion Control: Sachets deliver a fixed dose every time. This is especially important for pharmaceuticals (exact medication dose) and food/supplements (consistent flavor or nutrients). The tight seals prevent leakage or tampering.
• Strong Branding Opportunity: Even though sachets are small, their surface can be fully printed. Manufacturers can include high-resolution graphics, brand logos, and product information. Colorful sachet packs can stand out in the market just like bigger bags. The ability to customize sachet appearance is valuable for marketing and compliance.
• Потребительская апелляция: The single-use nature is perceived as hygienic and convenient. Consumers know exactly what they’re getting in each sachet portion. This can increase trust and satisfaction.

В итоге, sachets balance functionality and convenience. They let you give customers exactly what they need – and nothing more – in a durable little package.

Sachets vs. Stick Packs

Sachets are often compared to stick packs because both are small flexible packets, but they have key differences:

• Форма & Структура: Sachets are generally square or pillow-shaped with three- или четырехсторонние уплотнения, whereas stick packs are long, narrow tubes (often sealed with a back seal). The slim stick-pack shape is great for pouring powder products like drink mixes.
• Content & Универсальность: Stick packs are optimized for free-flowing dry goods (растворимый кофе, drink mixes, powdered supplements) because their narrow opening lets powder flow out easily. Sachets are more versatile and can package thicker products – pastes, гели, кремы, or sauces – just as well as powders.
• Packaging Speed & Материал: Stick-pack machines typically run faster than sachet machines. Фактически, production studies show stick-pack equipment can produce 30–50% more units per hour than similar sachet machines. Stick packs also tend to use slightly less packaging material per unit. This makes stick packs very efficient for high-volume, bulk powder applications.
• Потребительский опыт: Because sachets have a flatter surface area, they often provide a nicer pouring experience for non-powders and more room for labeling. Пакеты палочек, being slim tubes, sometimes feel more “rigid” to tear open.

Например, if you need to portion a viscous liquid or jam, a gusseted or flat sachet is usually the better choice. But if your product is a dry powder and you want maximum throughput, a stick pack may win on efficiency. На практике, many manufacturers offer machines that can do both by swapping films or settings.

Applications of Sachet Packaging

Sachets are used across many industries:

• Еда & Beverage: Single-serve sugar, salt, кетчуп, mayonnaise, chili sauce, заправка для салата, растворимый кофе, чай, and flavorings are very common in sachets. Think of the condiment packet with your fast-food meal or the instant broth mix – those are classic sachet packs. Snack food samples and nutritional supplement pills are also sachet-packaged. Because sachets are compact, they’re ideal for promotion giveaways and travel-size consumables.
• Личная помощь & Косметика: Shampoo, conditioner, lotion, маски для лица, toothpaste, and shampoo are often sold in sachets, especially as samples or travel kits. A single-use beauty or hygiene product in a sachet is low-cost for the manufacturer and appealing for trial.
• Фармацевтические препараты & Healthcare: Many medicines (порошки, гранулы, мази) come in sachets. Например, emergency medications, sterile wound-care creams, or pre-measured baby formula are packaged as sachets for safety and dosage accuracy. Specialized medical sachets use extra barriers and sterilized materials.
• Household Products: Detergent, cleaning wipes, and chemicals can be in sachets. Travel-size laundry detergent pods or hand sanitizer gel often use sachet packs.
• Other Industries: Seed packets, pet foods, and various chemical compounds use sachet packaging when small portions are needed.

Every time you see a tiny single-dose pack, it’s likely a sachet. Their convenience makes them popular for sample marketing and for products where single-use is important for hygiene or dosing.

Sachet Packaging and Filling Machines

Producing sachets at scale requires specialized machinery. Современный sachet packaging machines (often a type of form-fill-seal machine) automate the entire process:

• Form-Fill-Seal Machines: In a continuous process, sachet machines do three things in sequence:
• Form: A roll of flat film (laminate) is fed into the machine. The machine shapes and folds the film into a pouch shape (sealed on the sides and bottom).
• Наполнять: A precise amount of the product (жидкость, пудра, гранулы) is dispensed into the open pouch from above or side.

• Seal: The open top of the sachet is heat-sealed and cut off from the film roll, creating a finished pouch. The machine can also add features like tear notches or embossing codes in this step.
  This vertical form-fill-seal (Вффс) approach is very common for sachets. notes that VFFS machines (film moving vertically, product dropped from above) are ideal for powders, гранулы, and many liquids. There are also horizontal FFS (ВФФС) machines where film moves horizontally; these are used for flat, solid items or delicate products.
• Sachet Filling Machines: After (or during) forming the pouch, machines must fill it accurately. There are specialized sachet filling machines tailored to the product type:

• Жидкая начинка: For water-like or viscous liquids (соусы, масла, beverages), piston pumps or gravity fillers meter the fluid into each sachet. These systems ensure quick filling with minimal spillage.
• Powder Filling: Fine powders (кофе, detergent, spices, pharmaceuticals) are dispensed using auger screw fillers or vibratory feeders. These tools drop precise grams of powder into each pouch while containing dust.
• Granule Filling: Products like rice, beans, granulated sugar, or tablets are poured from hoppers or multi-head weighers. These machines cycle granules into the pouch evenly, often using conveyor belts or a dosing cup.

By combining these systems, a sachet packaging line can handle virtually any product. Например, a vertical sachet machine might use a pump filler for ketchup or a screw filler for powdered milk – it’s all integrated.

• Advanced Equipment: In many factories, additional machines complement sachet production. These can include rotary pick-and-place machines (for pre-made pouches), vacuum sealers (to remove air before sealing), Картонические машины (to pack sachets into boxes), и multi-head weighers for even faster granular dosing. Однако, the core sachet making still revolves around form-fill-seal and filling modules.

Sustainability and Future Trends

One major challenge with sachets is environmental impact. Traditional sachets use multi-layer laminates (например. PET/Aluminum/PE) that are excellent at preserving contents but are difficult to recycle. Once used, these packets often end up in landfills because the layers can’t be separated easily. Awareness of this issue is growing in the packaging industry.

To address it, manufacturers are innovating in eco-friendly sachets: – Mono-Material Sachets: These are made entirely from one recyclable plastic (like all-PE or all-PP). They aim to combine the needed barrier properties with recyclability. Research is re-engineering these plastics to match the protection of laminates. – Biodegradable/Compostable Materials: Some sachets now use plant-based films (such as PLA or PVOH). These can break down under industrial composting conditions. They offer a greener option for short-term use items. – Material Reduction: Simply making sachets smaller or using thinner film also helps. Moving some products to formats like stick packs (which use less film) is another approach.

The future of sachet packaging will likely blend convenience with sustainability. Watch for recyclable sachets и smart packaging designs. В то же время, advanced machines are being developed to handle these new materials without slowing production.
