医薬品ブリスターマシンの問題: 10 一般的な問題とその解決方法
6月 3, 2026
導入: Crushed or damaged blister packs are one of the most frustrating issues for pharmaceutical and health supplement 包装生産ライン. A ruined blister pack wastes aluminum foil, プラスチックフィルム, and other consumables, and creates extra work for your team to sort out defective products. If you’re new to this manufacturing process, ブリスターパックとは何ですか? It’s the sealed single-dose packaging for medications and supplements, and what is blister packaging? It’s the automated process that forms, アザラシ, and cuts these packs for blister pack medication and capsule blister pack production.
今日, we’ll break down the 5 most common reasons your blister pack gets crushed, walking through each production station from start to finish, with simple fixes to reduce waste and boost your blister packing line efficiency.
The first common culprit is misaligned guide rollers at the film pulling station.
When the blister pack machine’s guide rollers are not calibrated level, the PVC film will run off track. This misalignment creates crooked, uneven material flow, which directly leads to crushed blisters later in the sealing process. Even a small offset can ruin dozens of blister packs for pills or blister pack meds in a single production run.
修正: The solution is simple. Slightly adjust the guide rollers and calibrate them to be perfectly level. Keep the film centered and running straight through the line, and you’ll eliminate offset issues at the source. This quick adjustment is one of the most practical packaging solutions to avoid unnecessary waste in packaging blister packs.
The second issue comes from the forming station: insufficient air pressure during the blister cavity forming process.
When the forming air pressure is too low, the blister cavities form too shallow. カプセル, 錠剤, or other materials will bulge above the surface of the PVC film. When the line moves to the sealing station, these raised materials get crushed by the heat sealing mold, leaving you with damaged blister pack capsules and defective medicine blister packs.
修正: This is an easy adjustment. Simply increase and fine-tune the forming air pressure to match your material and film specifications. Proper pressure ensures the blister cavities form deep enough to fully contain the product, so nothing sticks up to get crushed during sealing.We, 金鹿包装機械, offer customized secondary forming solutions. 最初に, it resolves the issue of insufficient air pressure when producing deep blisters. 第二に, it supports custom blister depths up to 30 mm.
Third on the list is unstable temperature at the forming station, a frequent issue for blister pack packaging lines.
Temperature is a key factor in how PVC film forms into blister cavities. 温度が高すぎる場合, the film will warp and deform, and the shape of the blisters will be ruined. 温度が低すぎる場合, the film won’t form properly, leaving shallow, weak cavities that break or crush easily. Both scenarios lead to damaged blister packs and inconsistent product quality.
修正: Match the forming temperature exactly to the thickness and type of film you’re using. Most modern blister packing machine models have adjustable temperature settings, so you can dial in the right heat for your specific material to get consistent, well-formed blister cavities every time.
Fourth, misaligned forming or heat sealing molds are a major cause of crushed blister packs during the compression and sealing stage.
When the molds are not perfectly aligned, they will crush the blisters under the pressure of sealing. This is a common pain point on many older or low-end blister pack machine models, where mold adjustment is complicated and time-consuming. Even a small misalignment can create uneven sealing and crushed blisters across an entire batch.
The Jinlu Packing Advantage: Unlike most other blister machines on the market, our forming and heat sealing molds feature an integrated design with slide-in slots. This streamlined design makes mold alignment simple and fast. You can reposition and align the molds in minutes, ensuring precise, even sealing that won’t crush your blister pack for meds or health supplement packaging products. This is one of the key innovative packaging solutions we’ve built to reduce downtime and waste.
The fifth common issue is incorrect traction stroke parameters, which cause the mold to hit and crush the blisters.
The traction system conveys the PVC film through the equipment via accurately controlled incremental movements. If the traction stroke distance is off, the mold will not line up with the blister cavities. Instead of sealing around the product, the mold will land directly on top of the blisters, crushing them and creating defective medicine blister pack products. On many traditional machines, adjusting the traction stroke is a tedious, complicated process that requires extensive downtime.
The Jinlu Packing Advantage: 私たちの ブリスター包装機 highly simplifies this critical adjustment. The traction station adopts servo traction technology. It delivers precise traction without deviation, enables one-touch parameter adjustment via the HMI. 加えて, the packaging material will not retract when the machine stops. また, you can calibrate the traction stroke distance directly on the HMI screen, without complex mechanical tweaks needed. This digital calibration ensures accurate positioning every time, so the mold lines up perfectly with the blister cavities and avoids crushing your product. This automated packaging solution cuts down on adjustment time and reduces human error in daily production.
After addressing these 5 common issues, 一貫性が得られます, high-quality finished blister packs with no crushed cavities, wasted materials, or defective products. Our machines are built to deliver reliable, precise performance for pharmaceutical and supplement packaging lines, with every component designed to minimize waste and maximize efficiency.

の 5 most common causes are misaligned film guide rollers, insufficient forming air pressure, unstable forming temperature, misaligned forming or heat sealing molds, and incorrect traction stroke parameters. Each issue directly disrupts the forming, 封印, or material positioning process, leading to crushed or damaged blister pack products.
This is almost always caused by misaligned guide rollers. When the rollers are not calibrated level, the PVC film runs off track, creating crooked material flow that leads to crushed blisters later in production. The quick fix is to adjust and level the guide rollers to keep the film centered and running straight.
Shallow cavities that cause crushing during sealing typically stem from insufficient forming air pressure or unstable forming temperature. 初め, adjust the forming air pressure to ensure the cavities form deep enough to fully contain the product. 2番, match the forming temperature to your film thickness, meaning, too little heat will fail to shape the cavities properly, while too much heat will warp the film.
Misaligned forming or heat sealing molds apply uneven pressure that crushes the blisters during compression. Incorrect traction stroke parameters make the mold land directly on top of the blister cavities instead of sealing around them, crushing the product. On most machines, this requires complex mechanical adjustments, but our systems let you calibrate traction distance directly on the HMI for precise positioning.
Start with regular calibration of guide rollers, forming temperature, air pressure, and traction parameters to fix the 5 common issues we covered. For long-term stability, invest in a blister packing machine with integrated, easy-to-adjust molds and digital HMI calibration. These features cut down on human error and downtime, and are key parts of reliable pharma packaging solutions that reduce consumable waste.
