<\/h2>\nPackaging has long stopped being \u201cjust a bag.\u201d It protects the product, shapes the first impression on the shelf, and can even influence sales\u2014especially if you work with goods where cleanliness, appearance, and packing convenience matter: bakery items, snacks, dry groceries, fresh herbs\/greens, small textiles, or hardware.<\/p>\n
That\u2019s why polypropylene bags remain one of the most popular solutions on the market: they look neat, cost reasonably, and handle everyday operational loads. In this article, we\u2019ll explain what polypropylene film bags (BOPP\/CPP) are, why they\u2019re practical, which formats can be produced, and how ARTHA-S helps you choose the best option for your product and sales channel.<\/p>\n
<\/h2>\nPolypropylene bags for products are made from polypropylene films\u2014BOPP or CPP\u2014developed specifically for flexible packaging. In simple terms, it\u2019s the material that gives the \u201cclean, clear, glossy\u201d effect while staying resistant to moisture and many external factors.<\/p>\n
Typical polypropylene benefits include:<\/p>\n
The reason is straightforward: polypropylene offers one of the best \u201cprice\/appearance\/practicality\u201d balances.<\/p>\n
BOPP packaging film (biaxially oriented polypropylene) is that familiar \u201crigid, crisp\u201d material with high transparency and shine. It exhibits good barrier properties against water vapour, gases, and foreign odours, while also possessing high strength.<\/p>\n
Where BOPP is especially suitable:<\/p>\n
It\u2019s no surprise many BOPP film bags are made from this material: it looks great and performs well in mass-market categories.<\/p>\n
CPP packaging film (cast, non-oriented polypropylene) is more elastic and \u201csoft-crinkly,\u201d with high mechanical strength and transparency. It\u2019s resistant to acids and fats, seals well, and supports various printing types.<\/p>\n
CPP is often chosen when extra flexibility or specific processes are required\u2014for example, when a product requires sterilisation in a film of a specific thickness.<\/p>\n
A flat (straight) bag is a flat polymer bag of rectangular or square shape with three or four perimeter seals.<\/p>\n
Most common uses:<\/p>\n
Why this format is so \u201cwork-ready\u201d:<\/p>\n

Cone \/ Trapezoid Bags<\/h3>\nA cone (trapezoid) bag is a trapezoid-shaped bag with two or three perimeter seals.<\/p>\n
Most popular scenarios:<\/p>\n
The advantage is simple: it looks more premium, and clear glossy BOPP film enhances the \u201cclean and shiny\u201d display effect.<\/p>\n
Bottom-gusset bags have a fold at the bottom (roughly 2\u20135 cm), which increases volume and helps the bag \u201ctake shape\u201d and stand more steadily.<\/p>\n
Business value:<\/p>\n
Technical holes (8 mm) are holes designed to release air and moisture: up to 8 holes in a flat bag and up to 4 in a cone bag.<\/p>\n
Practical benefits:<\/p>\n
A reinforced seal is made as an additional sealing line parallel to the main one (often in a dotted pattern). This is used when there are higher requirements for side-seam tear resistance.<\/p>\n
Real-life benefit:<\/p>\n
A euro slot (hanger hole) is an area designed for hanging the bag on hooks\/displays. It\u2019s convenient for retail: the product is visible, not piled up, and looks neat.<\/p>\n
To prevent tearing in the hanging area, reinforcement tape is used\u2014it strengthens the euro slot, reduces the risk of breakage, and keeps the packaging looking tidy.<\/p>\n
A flap is an extension of the film above the main part of the bag. It can be used for closing (often with adhesive tape) or for bundling bags together (clips, tear-off flap).<\/p>\n
Business advantage:<\/p>\n
To make polypropylene bags that are not \u201cjust like everyone else\u2019s\u201d but tailored to your product and packing process, production capabilities matter. ARTHA-S covers key tasks:<\/p>\n
And an important point for smaller producers and packers: you can start with small batches. For example, clear flat and cone bags from 20 kg, and printed bags from 100\u2013200 kg (depending on specs and number of colours).<\/p>\n
